Wait wait wait, first of all:
CHEATERS ARE THE EVIL!!!
They have to be banned, kicked out etc etc... they must not be part of the game and people who run BB must deal with them, with the help of the community.
BUT (there is always a but), they cannot be an excuse for a free "killing" market where who only trades rule and who only trains suck. Cheaters are not an excuse for twenty transfers in a week, and daytraders are not cheater-buster (in fact, here and in HT I have seen many suspicious DT).
