So yea, It just popped into my silly head.

There's that afk penalty right? you lose 5k or something like that right?
but what if, the user only has 4k or below or something and he had the afk penalty, will all of his tc get lost or does he keep his tc? does his tc go negative or something? or idk, lol.

Lol it just become 0 TC,smosh

What if a guy who doesn't have tc keeps occupying the space and keeps entering and being afk in a tourney or a match or something and he gets autospeced and he doesnt lose tc, and he actually transfered all of tc to an alt or something, wouldn't that be annoying?

Marcus and I actually tested this a while ago, it seems that if you don't have enough tc, let's say that you've got 300tc and the afk penalty is 400tc, all that happens is you get specced. Your tc isn't removed but you are removed from the current game I'm 99% sure that's how our test came out.
