This is a rule violation, but it's fairly minor. A veteran forum member isn't typically going to be banned without warning for moving their topics incorrectly. (These topics were blanked and then deleted over the course of ~3 days before the issue was noticed. It wasn't part of an ongoing pattern AFAICT.) If he continues to move topics incorrectly, this would warrant a temporary ban.
Yes Retimov is a veteran member
[1.] He has long experience in stealing others work [even avoided ban for plagiarism],
a thief.
[2.] He has long experience in farming merit in the forum to position himself as 3rd merit earner [we were able to set him as a role model, Ratimov medals Ratimov],
a merit farmer.
[3.] He has long experience in manipulating DT system to positing himself with 14 DT strength,
a DT abuser.
[4.] He has long experience in conducting deals to grow his feedback page with +22 positive feedback,
a trust farmer.
[5.] He has long experience in using trust feedback to hostage the feedback sender to offer peace,
a feedback abuser.
We need a custom title for Ratimov: A veteran intellectual thief, merit farmer, DT abuser, trust farmer, feedback abuser. Just like this

Joking apart, what do you feel about his merit source status? You said yourself
This was a moderator getting tricked
What are the possibility of you not being tricked?
I think I was tricked with all his fake good if I supported his
merit source application [moved to trash I think], I also think many others who were supporting the same application tricked with all his fake good. He received the status and was using the source merits to create a fake community around him with the merit beggars.
see lots of personal involvement of some users in all that
Are you still going to give special importance in personal involvements or you now can see the other issues are more important than personal?
He received a warning from me. I wrote to him about his behavior and that in case he continues such actions, he will get a ban. I did not receive a reply, but his trash topics did no longer appear after my warning. I hope for his discretion.
You did what should be done, there are no late in correcting mistake. If you would do the same and used your brain before making everything so messy like it became now then no one would try to point the fingers towards you and the other mod. I really hope you will use this experience to learn a good lesson. All the best.
