So far i have seen no one deny this cheat and a lot of ppl ignoring it and continuously dig up past mistakes, cheats and whatnot.
I'm glad you want to keep it civil, but..
The main mistake of the past is making forum threads like "these guys cheat".
You know the community, you know about attitudes, you should understand that such topics will never be civil.
If you want to solve flag-CS-cheats, grab your evidences, PM to one of Grey's leader (I'm sure, you know that they are the few who can keep it civil) and those admins/devs, who can solve this problem.
But it's not your aim - solve it civil. Your aim is to "expose the trouth" about evil non-stop cheating UIF = start the drama.
