Do Something about Unwanted Whispers and Spam
I /block and then /report any scammers or gold sellers. I have never seen the same message more than once, except when I am in combat and can’t /block quickly enough.
Although ANet needs to verify reports, they often ban accounts within a minute of a reports.
Prohibiting certain phrases is almost never successful: it turns into an arms race. If ANet makes the phrase too general, it affects honest players. If ANet makes it too specific, the spammers make tiny modifications to the text. BannedText.com becomes BaNNedtext.com or Banned Text dot com (no spaces). Or they just get a new URL to use (tinyurl.com/feisty). At that point, ANet is spending far too many resources trying to maintain the banned list and fewer resources dealing with specific accounts or root causes.
