Yeah, there's some satisfaction in catching cheaters a full week after they've cheated, when they probably think they got away with it. The evidence is all there, though, and there's no question. It was deliberate cheating.
I have to say, though, that I'm more sad than anything. We want as many people in and racing as possible, so kicking out 5 people sticks in the throat a bit.
We've made a commitment to everyone that your STCC licence means you're "keen and clean".. and so when someone (or 5 of them) turn up to undermine that, the only way to address it is to remove them from the running completely.
