Mail services can filter out most spam, with a lot of it being seemingly normal mail, and I'm sure there are FOSS solutions for it out there, and if not, there exist dozens of algorithms that could be implemented. I mean, link-as-title spam could be deleted immediately, no question about it. As for the rest, at least half of it looks like markov chain generated text, not to mention virtually all of it has a huge concentration of buzzwords like random medical or cosmetic terms.And even if it's real users, which I doubt(names that seem extremely common in randomly generated spam names), they post their spam almost immediately(1-2 minutes) after registering, have no real profile info whatsoever save for perhaps the category the spam is relevant to, blah blah blah.I just don't buy this being impossible or even difficult to filter, I'm pretty sure I could code it myself.
