I agree with Mafia.

I dont agree with buying boosters on multiple accounts, however, it would make no sense for Nabi to make a rule that restricts any form of profits they make.
I understand that this much TC in circulation is bad for the economy etc, but that's just how its going to be.

TC sinks are something that need to be a bit more common and need to be inviting enough so that a higher amount of people will actually become involved in it, as thats the only way i can see this issue being fixed without the sacrifice of revenue.

So overall I dont agree with this suggestion, although i would love to.
