Hey Daniel,
Thought you users might get a chuckle out of the way I set it up.
I created a user called "Troll Stomper" and he's set up as the chosen "informant" member for both your Proxy RBL Checker and the
Multiple account login detector (AE Detector).
Now whenever your Proxy RBL Checker detects either someone using a proxy, or a spam bot trying to register...our Mods get this PM.
He also shows up in the Private Forum if the Multiple Account (AE) Detector gets tripped and posts the alert as a thread.
My Mods also had a suggestion that doesn't seem that relevant to me, but they said they would like to know what username the person or bot tries to use. I don't see how that info would be very relevant, but they indicated they would like it as it would help them recognize a problem user if they do manage to switch their IP into one that was not listed (basically recognizing them if they try using the same username).
Anyway, it's been great as it is not only stopping trolls trying to use proxies to bypass bans, but it's also stopping the spam bots right at the door as well.
