How possible is it for only one person to own these accounts. This is a way too much to control by one person. How did you make these findings. Assuming I'm a Russian, I would have followed up this allegations very well.
I suppose you have not yet seen scenarios where Signature and bounty cheats have been detected and dozens of accounts get linked to them like in this cases1. 1 man, 100 accounts NEED DT abusing signature/ facebook bounties
2. Help me to find the main account of this 30+ accounts abusers
3. A Large Farm of accounts cheating on signature campaigns
It also got me wowed at how determined people can be
Perhaps they even set up a mini company to just post on Bitcointalk for tokens
