I finally caved in and disabled tells completely. In all the pay-to-play games I have played, this is by far the absolute worst I have ever experienced. Never have I seen such harassment from RMT. I don't expect the game to be 100% RMT free, but I do expect not to be constantly spammed.

SE may be banning thousands of accounts, but just banning those accounts is obviously ineffective. My favorite solution is Sony's implementation of a Naive Bayes spam filter as described http://nandor.szots.com/Bayesian_Spa...ng_in_MMOs.pdf It's a fairly basic machine learning algorithm that they tweaked with a few modifications to take advantage of the extra information the service provider stores about the users.
