So like, I know this post is being old and probably a lot of you already have made a topic about it.
But seriously I don't see any serious results from square on that enormous issue.

1. for 100 RMT's accounts maybe 2 to 3 is being really taking care of ( by taking care : canceled account )
2. the reporting system is really bad. It takes way too long to my opinion to report an RMT, when a simple right click in "guild wars 2" was making it so easy and simple. I don't think I should have to spend 30 minutes a day writting a report on EVERY RMT shouting / whispering / yelling. We are paying for the service support to provide EASY tools for such issue.
3. the blacklist is leeking when you open it to write new names. I can have 2 RMT blacklisted spamming 2 shouts by the time it loads! On top of it, it's player unfriendly to use. Did you ever tried to spell an RMT player ? No then try it... have to pass by tell and macro to blacklist one guy.... seriously...

Out of all people I blacklisted ( only RMTs) only 7-8 were canceled... this is lame, i'm sorry for being rude.. but really... I will hit the 200 rmt blacklisted maybe in a few and I'm sure I will not hit 20 RMT banned...
