Wait what. I just realised that I'm getting charged every time I get a warning, and for people familier with me. I have had like 8. That's 20TBT per time... That's well out of order as sometimes I haven't even done anything wrong. Why are we not informed of this?
I wouldn't worry too much about the loss of TBT ^^. Fortunately, 20 TBT isn't that much and can easily be made back by posting - probably in 3-4 average sized posts, and it's probably set at 20 TBT to discourage users from violating the rules while not being too harsh for members who get sidetracked from time to time.
