I am not a student of advertising, but I really have to wonder: Does this kind of tactic actually bring in any business? Is there any value in trying to "foil" blacklisting? Presumably, if you send someone an advertisement and they blacklist you, it means they are not interested in your product. Are there actually people out there for which this is not true? People who will blacklist the first couple of times, and then turn around and say, "Oh, all right, fine. Since you asked me twenty-three times, I guess I'll go buy some gil!"

I would think that gil sellers' efforts would be better rewarded if they were to tailor their advertising toward INTERESTED players, rather than try to force their ads onto people who just don't care. If someone actually buys gil, gil sellers should dedicate an armada of bots to sending messages specifically to that player to make sure that they get word of every new deal! Preferably, many dozens of times per day. The gil buyer would appreciate that right? :3
