There are over 20 "Solutions" that would help alleviate, or get rid of the problem completely. These will never get implemented however, because SE gets money from the Gil Spamming accounts, and doesn't want to lose that revenue source. Secondly, it inflates their population numbers for management, and they don't want to go to their next meeting saying we lost X amount of accounts. And lastly, they haven't devoted ANY resources in the last 4 years to this issue, what makes you think they'll do so now?
