Second, I knew of some drama with merit sources, and some of them revoked to be a source but it happened in 2018 or 2019. What happened with Ratimov? I actually did not know about it.
Not much is known about what happened to him
[only he knows better about this than we do]. I just know that he hasn't spent much of his sMerit in the last few months but today 1 big deal was issued along with the confirmed that he is no longer the merit source on the link referred by @filippone. Really, I also think that he is an asset on this forum whether one likes him or not, and to be honest there are probably a lot of users who really miss his contributions right now.
To our merit source @filippone, congratulations on reaching your new milestone today. That 10K merit is something special to have.
