I have no elements of proof to say that "russians" multi-account or not, and I feel that many that say they do, do not have any proofs either.
It is one of the thing that has been repeated thousands of times, so people naturally think that it is true.
It may have been true at one time, maybe it is today, but until such a time where an investigator find conclusive proof, it would serve Strategus better if we all praised the power of the UIF as something that has been obtained with fairplay, because it might be the case.
I have entered only a couple strategus battles and where the UIF is one of the participants, everytime I see the same people accusing them of things they arent even sure, or they would prove it. We would enjoy Strategus more if we stopped seeing evil everywhere. Else do not be surprised if they answer you with sarcasm everytime, like Vovka and others are very famous for
