ToS terms don't grant you power beyond the law, nor can they shield you from complaints or lawsuits.
Of course, this is a no-name exchange with no location and no physical address but normally such ToS wound't stand a chance in any civil or criminal case.
Are you talking about law/legal in general or specific in Russia? Besides, there's another concern whether OP could be remain anonymous if OP decide to sue the exchange.
Could you explain why you said "It is clearly 100% money laundering"? While 94.89... is quite high, i wouldn't say that when doesn't meet 95% or 99% confidence interval.
This is what I do 14 hours a day. I have a big database which works like a spider and identifies several inputs which are already tagged as used in illegal transactions.
That only explain you have some experience and resource to classify UTXO. Do you imply 94.89...% is high enough to say it's definitely money laundering?
