The master created an AFC draft, Draft:Annwesha Hazra that never got off the ground. Mynameisparitoshmandal appeared a month or so later to create Draft:Hazraann (subject: Annwesha Hazra), and then pushed Annwesha Hazra into article space. Both are SPA. The master's very first edit was to add a COI box, if that tells you anything. --- Possibly ( talk) 10:14, 24 May 2021 (UTC) reply

Adding User:Alokchatterjee, creator of Draft:Annwesha. --- Possibly ( talk) 14:34, 24 May 2021 (UTC) reply

• @ Blablubbs: seeing as TryingToDo from group 2 reported the editor who is group 1 at COIN, I wonder whether this was some sort of training run through for paid editors, to demonstrate how we combat UPE and COI. Or it's competing companies. Of course, I guess we will never know. --- Possibly ( talk) 00:28, 27 May 2021 (UTC) reply

@ Blablubbs: I think you are exactly right. I recall now that Mynameispartioshmandal said something like "the editors who did the first drafts were not very good"! Makes sense. Thanks all around. --- Possibly ( talk) 00:47, 27 May 2021 (UTC) reply

Mynameisparitoshmandal said " Well she paid many people to create a page for her. But none of them were accepted. And that has nothing to do with my page." --- Possibly ( talk) 01:00, 27 May 2021 (UTC) reply

• Adding an obvious sock IP, editor of Annwesha Hazra, not sure how much can be done about it. --- Possibly ( talk) 07:16, 27 May 2021 (UTC) reply

Accused parties may also comment/discuss in this section below. See Defending yourself against claims.

• @ Possibly: I have added Myselfalok and GoyalAlokesh based on their contributions and editing pattern. Run n Fly ( talk) 19:21, 24 May 2021 (UTC) reply
• Also, to avoid doubt and WP:SCRUTINY, Alokchatterjee made a controversial move Nusrat Jahan→ Nusrat Jahan Jain Khan that needs to be un-done per WP:COMMONNAME (already requested at WP:RM). See their contributions. Similar action was also untaken by Mynameisparitoshmandal by moving Dibyojyoti Dutta→ Annwesha Hazra (this has been already rectified). See the diff here. Also, looks like WP:SLEEPERs need to be checked. Thank you. Run n Fly ( talk) 19:21, 24 May 2021 (UTC) reply

  Requesting @ Mz7, Oshwah, and Blablubbs: for futher help. Thank you. Run n Fly ( talk) 19:29, 24 May 2021 (UTC) reply

@ Run n Fly: Thanks. There is something odd going on; Mynameisparitoshmandal is a new account but reported me to AIV (sigh) using Twinkle. --- Possibly ( talk) 19:36, 24 May 2021 (UTC) reply

@ Possibly:, That's a weak argument as WP:OWNERSHIP is not allowed here. Run n Fly ( talk) 19:47, 24 May 2021 (UTC) reply

Possibly, Blablubbs and L235 now I can connect why I was targeted and WP:HARASS at Run n Fly are connected with Khorkuto serial because I may have end up TryingToDo and their scope of WP:PAID work here. In fact all were being done with proper planning so they never get caught and genuine contributors like me may end up losing faith and credibility. Thank you for catching the violators.

• Seems plausible given the shared interest in Annwesha Hazra and Dibyojyoti Dutta ( EIA), usernames and other editing patterns. That's quite a few socks, so  Clerk endorsed for a sleeper check and to look for prior accounts. -- Blablubbs| talk 08:58, 26 May 2021 (UTC) reply
  • On a sidenote, @ Run n Fly: It's usually not necessary to ping me to SPI cases unless it's urgent and you need me specifically (e.g. because you want me to run a proxy check or I'm exceptionally familiar with the master) – I usually read everything that's filed here within 24h at most. -- Blablubbs| talk 09:01, 26 May 2021 (UTC) reply

• Blocking the confirmed accounts in each group without tags.  Behavioural evidence needs evaluation. KevinL (aka L235 · t · c) 23:46, 26 May 2021 (UTC) reply
• Group 2 is more sophisticated behaviourally, and TryingToDo voted delete at Wikipedia:Articles_for_deletion/Annwesha_Hazra, an article created by Mynameisparitoshmandal, in addition to various other quarrels between the two clusters, indicating that these are warring factions, likely UPE. Splitting Group 2 to Wikipedia:Sockpuppet investigations/DasSoumik, moving this one. For this group:  Awaiting administrative action: Please block Alokechatterjee3 indefinitely – given that their username is basically identical to Alokchatterjee, who is confirmed to this group, plus the behaviour mentioned in the report, I don't think there's any room for doubt. Thanks. -- Blablubbs| talk 00:02, 27 May 2021 (UTC) reply
• @ Possibly: My best guess is that these are warring UPE factions – they also tried to get rid of each others' pages ( [1] [2]); some spamsocks get pretty mad when someone else gets the Upwork job they wanted. Another option I considered was that they are trying to present their own articles as "under threat" to get more money from their clients. Looking again in more depth and with the CU result, I'm pretty sure this is a freelancer turf war though. In any case, this might be worth a separate COIN post – the DasSoumik group wrote quite a few articles. -- Blablubbs| talk 00:44, 27 May 2021 (UTC) reply
• Oh, looks like Kevin got to Alokechatterjee3 despite not being confirmed – not sure why I didn't catch that at the time, though the mild sleep deprivation might have something to do with it.  Self-trout and  Tagged that one too. @ Possibly: I'm afraid I can't do much about the IP at this time. They've already been on one or two different /64s after the edits on the listed IPs – we could theoretically whack 2409:4060:2000::/36 ( talk ⁺ · tag · contribs · filter log · WHOIS · RBLs · proxy check · block user · spi block · block log · cross-wiki contribs · CheckUser ( log)), but I'm guessing that even that wouldn't hold for very long, and we'd be creating a good amount of collateral. The fact that there is logged-out editing is definitely worth noting for the future, though. Closing. -- Blablubbs| talk 09:52, 27 May 2021 (UTC) reply
