Have you or anyone actually seen/documented CP there?
Yes, I did see very questionable content on the chan when I was given a free MPEx account and was considering whether to invest or not. I wouldn't make an accusation like this without it having some weight. Needless to say I didn't invest and was absolutely disgusted and have no respect at all for this "company".
Other people have also mentioned seeing questionable content as well. I'm sure the chan mods delete it when they see it, but thats beside the point.
