I conducted a large-scale investigation, checking a huge amount of data, checking and comparing absolutely all accounts, and came to the conclusion that all these accounts belong to the same person. And now in detail and about everything in order.
..
In general, if we look at the list of accounts, then there are often very close registration dates, or similar nicknames. Sometimes the cheater lacked imagination and he repeated himself. For example: RainbowKun - Rainbow-queen, Louis Harper - Harper32, ROSEDF - ROSERTY. In general, the style of many nicknames is repeated and has a similar style.
If there is a bot farm, then what links it to RainbowKun? How do we not know that it is run by the very own Ratimov! Or any of the users that merited this post?? I am not suggesting any of those, but suggesting that the evidence is lacking. Suggesting that because he was merited by them is enough evidence is not sufficient. His account posted frequently. Merit sources also changed, so there was more recent merit given out, which you might expect.
They "absolutely have a connection"? Consider me skeptical of this statement unless you have hard evidence. It's a public forum for a topic over a decade old with a lot of publicity, when bitcoin has reached all time highs (again). There could be users that are connected with each other (e.g. ROSEDF and ROSEDTRY is likely the same person), but that does not mean a connection to the others.
What evidence do you have? You only posted that you did analysis -- but I don't see a description of that analysis. Would you describe it to forum members? Or describe it in more detail privately to admin/mods if you think that is better?
I will concede that what looks like FIRSTNAME LASTNAME user accounts are probably linked, as this was a common feature of account farms on reddit during several elections. It is also unlikely for people to use their firstname lastname as a user account, although not impossible if due to an external (albeit dumb) campaign.
