Good point on the "money for terrorism". I personally find it ridiculous that its attached to "money laundering/ ..." in every official instance (big fish and 99.9999% are still just illegal non-terrorist business id guess), but thats the state we are at , with all the resulting paranoia.

The problem for TAiS46 is probably that if there are even a few suspicious transactions (as the example he has given, money from hacked bank accounts being wired to his account to buy BTC), the only thing he can tell authorities is that his site made it disappear anonymously (not having used verification). So its hard to convince them he actually didnt have anything to do with it, and innocent until found guilty is a bit problematic in application if he is (probably) found in violation of regulations.

And yep, BTC wise, if he manages to sort out the multi-transactions (just some time/help) he should technically be able to send at least the majority of them back.
