My initial thought on that was, I can immediately ban users who register multiple account in a short time frame and starting uploading edgy/illegal images with CP Ads in them. I see this happen currently on a famous russian image site. Their moderation team can barely keep up with this Sh** and several albums are even online for days. If this would happen to my site (I host in Germany), the only thing I could do is to shutdown. I don't have that kind of moderation power.
But I realise now, that my request is not a solution to this problem. So, it is "-1" for me now. I don't need this at all.
