Straatmeester is an LTA who's already active on Wikipedia since 2008. His main account was blocked on the Dutck Wikipedia in 2014 because of his characteristic behaviour. The account was later globally locked in 2015. Since then, Straatmeester has been active as a cross-wiki sockpuppeteer, who showed special interest in topics related to MMA, the Rotterdam area and Surinam. Straatmeester's latest sockpuppet, Jackzin233 was globally locked on 3 december, following investigation on the Dutch Wikipedia. Furthermore, Straatmeester often continues editing from IP-adresses (see also the corresponding file on nl:WP:LSV/Straatmeester for more information). On the 4th of December, Bebfyce12 was created and continued the work of the latest Straatmeester socks. First, as its second edit, the account jumps in to defend an article created by another Straatmeester sock, that was moved to the Draft namespace the day before (see here). Second, Bbfyce12 shows similar interests as Straatmeester's other socks (MMA to name one). Third, the account immediately begins working on a cross-wiki basis (on articles in the field of interest of Straatmeester), which indicates that this is most likely not a new user. CU-requested to check whether any other sleepers are present on en-wiki and whether this account could be linked to edits by IP-users. Daniuu (talk) 10:29, 12 December 2020 (UTC)

First five accounts have already been confirmed as sockpuppets of LTA Straatmeester during earlier investigations (on nl-wiki or through a behavourial check by a steward). The final account is created shortly after Bebfyce12 is globally locked. Vresku5 shows cross-wiki behaviour that's extremely similar to the one typically displayed by the other socks: edits on the articles of MMA (which are mostly edited by Straatmeester socks - see for example here and this one on nl-wiki). Requesting CU to check this technically and for an eventual sleeper check. --Daniuu (talk) 14:45, 31 December 2020 (UTC)
 * As I indicated above, all accounts (apart from Vresku5) were previously confirmed as socks of Straatmeester, so in my opinion, they don't require further behavourial investigation (the SPI case could accordingly be closed). I'll request a global lock for Vresku5. Thanks for the quick handling of this request. --Daniuu (talk) 19:42, 31 December 2020 (UTC)

The previous sock of Straatmeester was blocked (and globally locked) on 31 December. This new account was created on nl-wiki and became active from 2 January onwards. It shows an edit pattern similar to the previous bunch of socks (see also nl:WP:LSV/Straatmeester). More specifically, the account most often edits articles on Surinam-related topics (culture and religion for example) and MMA. The edited articles are sometimes edited by nearly only previous socks of Straatmeester. Requesting CU to check whether any other accounts are present. Daniuu (talk) 12:13, 18 January 2021 (UTC)

The latest sock of this LTA was globally locked on 19 January. This account was created on the 1st of March and immediately started cross-wiki editing of pages related to Surinam and MMA. Some of these pages have been edited by earlier socks of Straatmeester (like the page 'Kaukakisch ras' on nlwiki, Jairzinho Rozenstruik, Regian Eersel). Requesting CU to check whether any sleepers... would be present. Daniuu (talk) 16:04, 6 March 2021 (UTC)

Accounts show the typical behaviour and interests of Straatmeester (see here for a more detailed description of this LTA). The latest Straatmeester sock was bagged on 12 March 2021. This account is created shortly after on 25 March. The user starts contributing on a cross-wiki basis quickly (contributions on enwiki and trwiki as soon as 26/03). Additionally, the user's interests match with those exhibited by Straatmeester and his previous checks (being Surinam, the Rotterdam area + Feyenoord and kick boxing). Some articles were also previously vandalized by Straatmeester's socks (such as this page and the article on Suriname and this page on ptwiki). Given Straatmeester's history of mass socking, I'd like to request CU to check for eventual sleepers. Daniuu (talk) 16:08, 5 September 2021 (UTC)

Straatmeester has a habit of editing articles related to kickboxing. His latest sock, Jeff090, got blocked and locked. One red flag is the fact that the IP edited Badr Hari, which was targetted by the earlier socks of Straatmeester on both the Dutch and English Wikipedia. There is also a second red flag, namely the logs for the IP on the Dutch and English Wikipedia. Daniuu (talk) 18:10, 24 October 2021 (UTC)

 * The IP seems static - it's been editing kickboxing articles since April of this year with enough similarity to the recent socks to convince me it's the same person. Blocked six months, closing.  Girth Summit  (blether)  13:40, 28 October 2021 (UTC)

A typical case where one sees a lot of Anas platyrhynchos. The request is inspired by the account's interests in MMA and Afro-/Dutch people, typical interests of Straatmeester. It's also significant that the account started editing shortly after a previous CU (see also the account creation). The cross-wiki behaviour is also notable (with ducky edits on nlwiki and these frwiki edits on a subject known to be frequented by Straatmeester). Could the checkusers verify the technical relation with the previous socks and/or run a sleeper check? Daniuu (talk) 17:03, 11 November 2021 (UTC)

Sjoerdk43 was CU-confirmed to Straatmeester by the checkusers on the Dutch Wikipedia (see also this CU-request) a few days ago. I just ran into a second suspicious account (Frederikcq12). A few things are rather special for this account. First, a strong similarity in the structure of the usernames of this accounts and previous accounts is observed. Second, Frederickq12 shows similar interests as the older socks (see for example this Surinam-related edit, this MMA-related edit, here and others). Additionally, Frederikcq12 starts editing on a cross-wiki basis swiftly (as can be seen from their CentralAuth), editing pages like this one, which were frequented by previous socks etc. Daniuu (talk) 17:42, 5 February 2022 (UTC)

 * Comparing against the notes on CU wiki, Frederickq12 looks exactly like Straatmeester. Blocking, tagging, will request locks. Sjoerdk43 is already g-locked, no action required here. Girth Summit  (blether)  12:56, 6 February 2022 (UTC)

This request is once again caused by a combination of factors. First, the new account shows (like other socks of Straatmeester) strong interest in topics on MMA and Suriname. Additionally, it is rather remarkable that some of the pages edited are also (and sometimes almost exclusively, like here, and this one) edited by previous socks: like here. Finally, the new account quickly starts editing on a cross-wiki basis (like here on ptwiki where they edit a previous article of theirs & this to give just two examples). Could the checkusers please verify whether this is indeed a sock and/or verify whether any sleepers would be present? Daniuu (talk) 12:09, 24 June 2022 (UTC)

Dutch IPs (Gemeente Rotterdam ISP) in tight range using Restoring sock edits on many articles.

193.176.221.239:

193.176.221.238:

Very little to no collateral from blocking the range, a range of /28 would only be them, and the /24 also doesn't really have anyone else. They are stable on this range for a while, this edit from April 2021 is probably them as is this one from February 2022 that was restored by a sock in June.

Also the [/24 range is range blocked on the Dutch Wikipedia, and the talk page of the IP has a link to discussion connecting it to Straatmeester. The discussion there has .236 through .239, as well as .101 .102. [[User:Pikavoom| Pika voom ]] Talk 08:15, 8 July 2022 (UTC)

The same story as always: when a Straatmeester sock gets locked, the next one quickly appears. The new account picks up the same habits as its master: immediately starting editing on various projects. The edits also fit the traditional pattern (on kickboxing-related topics that were previously visited by other socks: like this, this, and this one). Requesting a checkuser to have a look for eventual additional sleepers and whether or not additional blocks would be required. Daniuu (talk) 10:22, 25 July 2022 (UTC)

 * Urgh, SPI conflict again Roy. I've already blocked, tagged as suspected and requested lock. Girth Summit  (blether)  13:25, 25 July 2022 (UTC)
 * Yup, thanks. Nice to keep bumping into you like this :-) -- RoySmith (talk) 13:32, 25 July 2022 (UTC)
 * PS, I can see why you tagged as suspected, but I think there's enough to justify calling it confirmed. -- RoySmith (talk) 13:34, 25 July 2022 (UTC)
 * Fair enough - I didn't dig too deeply into the archived socks, I'm sure you're right. Girth Summit  (blether)  14:04, 25 July 2022 (UTC)
