Actually spammers do have a message boards, you just need to know where to look. The last issue was then Craigslist starting requesting phone numbers for certain ads, and they were working it out. SO they have more than one by the way. A lot are bots but then when you get certain impediments to their business they get together and work out solutions, it is a job for many, not one I admire but it is a job. Oh I will not post any address to them, I read them for my amusement, if you use your cunning they can be found along with the real hard core black hat sites, not the script kiddy ones.
