would suggest appealing next time you feel as if you've been falsely banned, a better way to discuss it than to post pointless profile comments on Purple's page about it as this will not help you get unbanned. http://forums.manacube.com/forums/ban-appeals/
If that shouldn't be a rule then whats the point of screensharing? "oh yeah sorry I've got a hacked client in this folder but I don't use it on manacube so its okay you can believe me."
