You know, there wouldn't be a witch to hunt if the people in charge would officially say anything definite. At this point in time, we have DH saying they will take strict measures against cheating at DHW - even though all hackers are already caught? And we have big figures of the scene (Pita, Xizt, HeatoN) and the coder himself and smn, and another guy who has legit sources saying there are more professionals cheating.
What do you expect people to do? Just go on as usual when rumors say the whole scene is a lie and people actually start getting banned a day after, in a very strange manner, and then the bans suddenly stop, even though the guy that helped initially expose the cheat at ESEA says he thought there were more bans coming?
