I normally play on Hyperion, and have not seen a single one there, but in order to play with my brother, i had to make a character on Pheonix. The second I entered Ul'dah, the chat was flooded by gill seller messages. The account for the gil seller Docette Orslfaux, who consistantly spams the website ff14goldmall.
Please, don't let this game end up like games like aion, where you can't go anywhere without being bombarded by this crap.
