1) Practically nobody without any ties to the area has ever been or likely will ever be a regular on this forum, or any forums on your side that I could name. If some outsider really wants to learn about Greece, there are hundreds of other sites one would go to. Only a complete fluke would send someone here.
2) The big-time spammers have been at it here for at least the last two years. You've been here for far longer (five years?), and suddenly now this is a problem for you?
3) The only way to get rid of the spam is for the administrator to act. He has shown absolutely no interest in editing this forum save for removing the occassional post featuring extremely pornographic pictures. I was banned twice from Bill Nicholov's old M-4-M forum simply because he didn't like my opinions, and I was never obscene and never spammed. Given these two extremes, I'll take the total freedom of this forum.
4) We all have three options: learn to live with it, reduce our visits here, or stop visiting here.
