To the best of my knowledge, MODS have no access to the private messages (Since they are private)....
So we'll just have to wait and see what they're planning.
CI, you've dealt with all this before. I know that you, as well as myself and other mods, have spent countless hours going through lists like this and deleting obvious spammer profiles. I suppose I could do that. But it's time consuming and I honestly don't have the time right now.
I've also realized, as I believe you have realized, that I really cannot put a dent in it myself. The owners of the site don't view it as an issue. I could spend hours deleting everyday, and they just continue to sign up. I try to catch the spam posts on the site, as well as spam posts reported by members.
Wish there was more that I could do, but I haven't found it as of yet.
