See this edit where Mantanmoreland adds to a Tom Stoner statement while saying "revising previous response"

One account uses nothing but open proxies, per the CheckUser result. That means any cross over would be minimal at best. IF the two accounts were used at the same time, any one slip of the open proxy account using whatever IP's the other account is using would give things away if a CheckUser was done. Since there was no non-open proxy use by one account, either there were:

A)No slip ups (most folks eventually screw up, and one edit from a non-open proxy would link the two accounts, so this option may be deprecated slightly)

B)If there's no cross-over, there's a possibility of a two different machines/setups, so a controller would not ever edit at the same time.. either at one machine or the other, but never both at the same time). Both accounts had roughly the same median edit time per Ioeth's analysis via the comparison tool, so a lack of cross-over would be suspicious but not proof.

C) If there's significant crossover, then that may point to a truly unrelated result.

Time stamps


Time stamps: I received a data dump of all of Matanmoreland and Samiharris's edits in Excel format, sorted by date. While this is not proof of anything by itself, there are no periods where the two accounts edit at the same time, it's all chains of one editor, and then the other. Going back to 12/30/07, for example, here is the time stamps of edits, and who did it: Samiharris	30 Dec 2007 19:39 Samiharris	30 Dec 2007 19:45 Samiharris	30 Dec 2007 19:45 Mantanmoreland	30 Dec 2007

This is only a period of five weeks, but the theory holds going back further.

Edit totals in 2006 and 2007
From the period of 2006-01-28 (Mantanmoreland's first edit) to 2007-01-29 (Mantanmoreland's last edit before Samiharris account was created) Mantanmoreland had 3538 non-deleted edits. From the period of 2007-01-31 (Samiharris's first edit) to 2008-02-03 (Samiharris's latest edit) Mantanmoreland had 1667 non-deleted edits, a decrease by nearly 2000 edits. Samiharris has a total of 1400 non-deleted edits over the lifetime of the account.

Roughly speaking, the combined output of the two accounts in 2007 nearly equals (within 500 total edits or so) the output of Mantanmoreland alone in 2006.

Coincidence of editing
By my count, there is a total of 75 days on which both Mantanmoreland and Samiharris edited. On only 5 of those days do their edits "interleave" with each other. (I consider edits to interleave if one editor edits during an apparent string of edits by the other editor. I consider edits to be strung together if there is no more than a 30-minute interval between edits by the same editor.  Thus the pattern is ABa, where A and a are part of a string of edits by editor A and B is at least one edit by editor B.)

These dates are:
 * 2007-02-09
 * 2007-05-14
 * 2007-06-28
 * 2007-07-29
 * 2007-09-15

The closest the two accounts' edits come is within 3 minutes of each other, on 2007-07-29.

Analysis
The pattern suggests that the two accounts draw upon the same basically fixed resource for editing attention. In fewer than 10 instances over the span of an entire year, with over 3000 edits between them, do the two accounts edit within the same narrow time frame (30 minutes of each other). The reduction in output by Mantanmoreland is nearly offset by the new output of Samiharris.

This is not by itself conclusive of sockpuppetry. It's possible that these patterns could be exhibited by two unaffiliated accounts. A control group is needed, either of similar comparisons between known unaffiliated accounts, or of a randomly drawn sample of accounts with similar output and account activity overlap, to show empirically how far from the norm this pattern of editing is.

Further information
Additionally, here's some further information found by reviewing the pattern of edits: (please note: 99.9% of this section was submitted to me by Durova, and is used with her permission:)


 * Chop stock:

Article history: 12 of 29 total edits to this article were made by Samiharris and Mantanmoreland from 16 July to 31 July, 2007. The article was created 16 June 2007 and merged/redirected to "Microcap stock fraud" on 31 July 2007.

The entire edit history of the article talk page is these two accounts agreeing with each other about a merge, posting 10 hours apart.


 * Short and distort:

Less than 50 total edits in the article history, 14 of which come from these two accounts. Unlike "Chop stock", their involvement spans a longer time frame. Mantanmoreland redirected it to "Short (finance)" on August 7, 2007.

A few points:

First edit by Samiharris, 21 March 2007 - prods the article (unsuccessful)

On 5 July, Mantanmoreland suggests a merge/redirect to "Short (finance)" Sami Harris agrees two days later. These are the only two editors who discuss merging the article elsewhere.
 * Pump and dump:

On 30 July 2007 Mantanmoreland proposes merging this into newly created "Microcap stock fraud". This is an older article than "Short and distort" or "Chop stock" and has collected a couple hundred edits since July 2003, yet Mantanmoreland redirects it the next day without any talk page response. Both accounts have been editing the article. Talk:Pump_and_dump


 * Thom Calandra:

Less than 50 total edits since the article was created on July 2007 until the present. Yet Samiharris's only post occurs 16 hours before Mantanmoreland's 12 posts on July 29.


 * Microcap stock fraud:

On July 29, both accounts essentially start this article in tandem and then go about merging other articles they've edited into it.

Interesting coincidences:

So is this collusion or two editors with similar interests and opinions? One way to gauge that is their communication.

The only edit at Talk:Microcap stock fraud:

This article, while describing a genuine phenomenon, threatens to duplicate other articles such as pump and dump and chop stocks and maybe others. You may want to consider a merger, perhaps of those articles into this one, or vice versa.--Mantanmoreland 20:04, 29 July 2007 (UTC) In addition to that I checked the histories of Sami's and Mantan's posts to each other's talk pages. You've both got the dumps on the total posts: 7 by Sami to Mantan's talk page, 6 by Mantan to Sami's talk page. That seems low for two people who share so many interests, although it's possible for two people who e-mail or chat offsite. These are the specific posts where they discuss articles:

21 June, Sami to Mantan – requests advice on short and distort 2 posts: Mantan, to Sami about Naked short selling

Mantan to Sami about Gary Weiss

Mantan to Sami about Microcap stock fraud, pump and dump, and chop stocks. Suggests redirect. So the mergers are discussed onsite. And two editors editing the same articles happens sometimes. What's missing in this picture is how Mantanmoreland came to the Microcap stock fraud article five hours after Samiharris started it, and why Mantanmoreland took such an interest in the Thom Calandra biography just a few hours after Sami Harris's only edit to it.

Without further context, the above edits are explainable. I'm very interested to see whether that check of the edit times actually bears out over the entire account histories. If they never edit at the same time, and one always uses open proxies, then my eyebrow is definitely raised. The next question would be seeing what scenarios and tests could disprove this appearance. Could they be different people on different work schedules?

When we proved BooyakaDell was JB196 two things were very strong evidence: both accounts consistently used the same misspelling in edit summaries, and BooyakaDell attributed a citation to Jonathan Barber even though the article didn't have a byline. We need a smoking gun here. This is serious stuff, and if Sami Harris isn't Mantanmoreland then these two guys have had more than enough headaches already.

Double !Votes and Dual ArbCom discussion
If this is proven to be a match per DUCK, this is the problem. The two accounts have both taken the same position in the following "!votes" and would be in violation of using multiple accounts in an ArbCom case

Articles_for_deletion/Investopedia Requests_for_adminship/MONGO_2 Articles for deletion/Judd Bagley (2nd nomination) Wikipedia_talk:Requests_for_arbitration/Attack_sites/Proposed_decision

There probably is others, but going through 6500+ edits, even using the tools made available to me, it's hard to find needles in 7000 or so edits worth of haystacks without multiple hours of work)

Also considering the history brought up by Viridae (That Mantanmoreland had previously been let off with a warning by Fred Bauder for editing the same article with multiple accounts previously), is another bit of data that needs to be considered

Before I get accused of ambushing Mantanmoreland with this information: Please note that he came to my talk page earlier today and was asked by Durova about this evidence,, but he refused to respond to this request by someone who had no "WR-Axe" to grind on this issue.

Conclusion: Especially considering the median edit time, there is VERY strong circumstantial evidence that the two accounts are linked. For two accounts with such a common interest and common edit times, not to mention common targets (admittedly, a target who has them in common as well), surely at one time or another in over a year and a half they would both be editing at the same time, and their edits would overlap at some point (IE, Editor A/B/A/B in short order...) instead of what we have which is always A/A/A/A/A/A and then B/B/B/B/B then back to A, etcetera. Combined with the common interests and the fact that never do the two accounts find themselves on opposite sides (in other words, they're always supporting each other's actions and arguments), this presents a compelling (if admittedly one with no one "Absolute Proof Smoking Gun") argument that per WP:DUCK, yes, these two accounts are related.

Updated list by FT2
A comprehensive list, covering both debates involving !voting, and other articles edited in common (excluding user talk pages). As stated by SirFozzie, on many of these, both accounts were used in the same brief timespans, and hence probably in the same debates. Further examples, eg. FT2 (Talk 05:10, 13 February 2008 (UTC)
