This whole thing is testament to the level of paranoia we now game under, the stance of innocent until proven guilty is no longer considered with many people even going as far as to be happy to ban people who are using it, in an innocent capacity (and that includes people who dont know there's even a problem) so long as they catch the "few" that are using for dubious means. Its completely the wrong attitude to have in my opinion and Its good to see GGC have followed PPBans lead on this.
It reminds of an quote made by the Abbot of Citeaux when discussing how to deal with the Cathers when he announced "kill them all god will know his own!".
Quality over quantity and I would personally rather deal with an army of cheats than having innocent people banned.
