It's truly too bad this game doesn't have a fiction that allows you to block an account entirely. Many of the MMOs I've played in the past (mostly those with global ID handles) had something like this available. Now, I'm not saying this will address all the RMT problems, but it will limit the amount of tells a player will receive until the account is banned. Most RMT have access to multiple accounts but multiple characters on each. Spam. Switch. Spam. Switch.
