Oh, there is another thing that I urge you to research. If you go by the constitution and the spirit it was written in (as in, all people are essentially good, whatever that word means), the exchange that accepted those tokens is also liable for aiding in theft.
That was my reason for saying that freezing those accounts is unnecessary, just to inform everyone not to accept any transactions involving them, as that opens you personally to liability. That is not censorship from BPs, but self censure in the spirit of the constitution.
I'd also like to urge whoever was that whose account money were moved to go to arbitration against the exchange in question. Blockchain makes it trivial to see which exchange it was (and some exchanges are also Block Producers), so they should know better.
