RMT can send tells to a character that was JUST created mere seconds after creation.
How? How could they possibly know that character exists before it even sets foot in-game? These characters aren't normally visible to the general population until after they finish those cutscenes, then leave the instanced zone.
I listened as, maybe 5 seconds after the new character's very first cutscene started, multiple tell sound effects rang out before the chatlog even appeared. Oh, and by the way, you can't blacklist them when the chatlog appears, either. Yep, you get to sit through the opening cutscenes while enduring tell after disgusting tell.
The fact that RMT can know of a character's creation within seconds speaks worlds about how horribly they've hacked this game. And how powerless SE is to stop them.
