Ron liebman (8th)



 * Code letter: F


 * Supporting evidence: More of the usual Liebman stupidity. A couple were quasi-sleepers so I'm hoping to catch a drawer of unused socks or a blockable IP.  —Wknight94 (talk) 03:43, 31 December 2008 (UTC)
 * The following are ✅ as Ron liebman:

I've also blocked the IPs. I guess Ron's back using library computers now. He hadn't popped up in my recent scan of his university IP range. Nishkid64 (Make articles, not wikidrama) 06:29, 31 December 2008 (UTC)
 * The rest are blocked and tagged. I had a feeling there were a bunch of sleepers!  Thanks.  —Wknight94 (talk) 12:32, 31 December 2008 (UTC)

Ron liebman (7th)



 * Code letter: F


 * Supporting evidence: Fits the pattern of the banned User:Ron liebman and his many sockpuppets - introducing unreferenced trivia into articles; and impersonating another user - in this case the since-retired admin User:IrishGuy. Made a couple of edits a year ago, then nothing until today. Articles edited match those frequently edited by Liebman. I've been advised by admin User:Wknight94 to file a checkuser request. The guy should be blocked in any case for the impersonation. Baseball Bugs What's up, Doc? 04:41, 30 November 2008 (UTC)
 * Formatted and moved from another case. —Wknight94 (talk) 04:57, 30 November 2008 (UTC)
 * Recommend a sleeper scan as well since the last one worked so well below. —Wknight94 (talk) 05:02, 30 November 2008 (UTC)
 * ✅ the following:

Nothing on the Ron liebman sleeper check, but I did spot a few new Koov socks (already blocked) since my last check on that IP range. Nishkid64 (Make articles, not wikidrama) 07:25, 30 November 2008 (UTC)

We haven't done this in a while so I thought it might be a good time to look for sleeper socks and maybe an IP or two. is an old banned user that has haunted Wikipedia for a few years now. He has continued to create socks at an impressive rate and has gone from simple misinformation to downright harassment and feeble impersonation attempts, geared mostly at, , , and. Above are just a few of the most recent at Category:Wikipedia sockpuppets of Ron liebman and I've deleted dozens of others per WP:DENY. Any help would be greatly appreciated. —Wknight94 (talk) 19:44, 8 November 2008 (UTC)
 * ✅ the following as Ron liebman (who coincidentally is operating on the same IPs as ):

Heavily used IPs also blocked. Nishkid64 (Make articles, not wikidrama) 08:05, 9 November 2008 (UTC)
 * He snuck in a couple more. Another IP check?  Other socks?
 * —Wknight94 (talk) 22:46, 11 November 2008 (UTC)
 * Both of those ✅, along with . I'm softblocking the most-used IP range for a week. that  is a match with Koov, based on technical evidence, but looking more  after mixing in behavior. –  Luna Santin  (talk) 23:41, 11 November 2008 (UTC)
 * And I think you saw the latest batch. Anymore hiding in the drawer?
 * You won't mistake Liebman for Koov. Liebman is a one- or two-trick pony.  You've seen just about all he has to offer. —Wknight94 (talk) 01:38, 12 November 2008 (UTC)
 * Err, the last 3 sounds quacky enough. OhanaUnitedTalk page 03:25, 12 November 2008 (UTC)
 * What a freaking nuisance. The next time someone says to me, "Hey, why don't you try for adminship?" I'll just send them to this page. Baseball Bugs What's up, Doc? 03:33, 12 November 2008 (UTC) (The real one)
 * I know they're quacky, and they're already blocked. I'm hoping to empty the entire drawer and find any underlying IPs.  It's been years now.  —Wknight94 (talk) 04:23, 12 November 2008 (UTC)
 * No sleepers from the latest check. Nishkid64 (Make articles, not wikidrama) 04:41, 12 November 2008 (UTC)

Ron liebman

 * (already blocked)
 * Code letter: F
 * Code letter: F

This is a single purpose account with edits picking up where User:KrazyChicken left off. This is indicative of behavior.


 * This was added to an already completed case that had not been moved yet. In order to make the second request look not already completed, I had to archive the old case.  Also did some formatting. MSJapan 15:49, 20 August 2007 (UTC)


 * ... not because they are not related, but because it is obvious that they are related!!! Just look at the contribs.

No checkuser is required here. CU is only for the most difficult cases, this is a very obvious case. (I blocked Robustelli too) Remember WP:DUCK, and remember that probable socks, based on the preponderance of evidence, are blockable and no CU is required. ++Lar: t/c 01:11, 21 August 2007 (UTC)
 * Soon after KrazyChicken is blocked, up turns Maf udding... what are the edits? setting Phil Rizutto's birth year to 1917. Even mentions Rob liebman in summaries

 * Identical style: birth year dispute, no source citations to support assertions..  Frequent reversions (but no technical violations)  Rklawton 15:40, 18 August 2007 (UTC)
 * formatted entry -- lucasbfr talk 20:35, 18 August 2007 (UTC)

✅. Also the following users are very likely socks. Still using NY public library terminals, as before, so other users on the IP with clean contrib records would suffer collateral damage if we blocked the underlying IPs...Hope that helps. ++Lar: t/c 22:30, 19 August 2007 (UTC)

New new accounts (post latest Ron Liebman request for unblock)



 * Code letter: C, E, F.


 * See also: Long term abuse

Ron has recently popped up on his talk page ( User talk:Ron liebman ) asking to be unblocked and apologizing and claiming that the flood of lookalikes really were not him. See also AN discussion: WP:AN

While discussions were underway there, two more apparent socks have popped up today ( and  ).

For the record, and to try and disambiguate the unblock request claims of Ron not being associated with the others, I would like to request a Checkuser check on the accounts used between the previous CU and today, including the two recent socks which appeared since Ron started asking for an unblock.

Thanks. Georgewilliamherbert 20:50, 11 July 2007 (UTC)

✅. All straightforward socks. Some proxy server use in there, so stay on the look out. Voice -of- All  12:57, 13 July 2007 (UTC)

Main IP blocked.  Voice -of- All  12:57, 13 July 2007 (UTC)

 * Code letter: C

Pretty much all of the contributions seem to match the style of the blocked user. Unsourced edits to baseball-related articles, usually involving statistics or "recent research". Wafulz 15:44, 30 May 2007 (UTC)
 * ✅. New York Public Library public terminal user. --jpgordon&#8711;&#8710;&#8711;&#8710; 15:53, 30 May 2007 (UTC)

Ron liebman





 * Code letter: C, E, F.

"Ron" (and accomplices?) have been widely vandalizing mostly baseball articles (Suspected sock puppets/Ron liebman) for roughly 2 weeks. Many of the edits have come from IP addresses known to be at New York City public libraries. I would like to run a confirmatory check on the named accounts to verify that this is all one incident. This may be unnecessary; most of the accounts above are indef'ed already by me; but given that the incident is still active as of yesterday and today (new account yesterday, IP vandal today) I think it's worth confirming with CU. Georgewilliamherbert 20:42, 21 May 2007 (UTC)


 * This doesn't meet C, E, or F. No diffs for vandalism or 3rr. Ron liebman isn't banned either. Request is not compliant. Fun  pika  23:24, 21 May 2007 (UTC)
 * [[Image:Symbol comment vote.svg|20px]] CheckUser note: No wonking please. This guy is banned enough for me; what are you looking for, the police report? I'm looking at this. :-) Dmcdevit·t 07:57, 23 May 2007 (UTC)
 * I misread codeletter F. Sorry! Fun  pika  10:20, 23 May 2007 (UTC)

✅, and and  as well. Dmcdevit·t 08:05, 23 May 2007 (UTC)
