I finally did it... disabled tells with busy status. RMT unbearably bad.

We all can give SE sugestions on how to deal with RMT and improve our spam experience, or SE could just instantly ban anyone who sends 100 tells to ppl at the same time. Let's be honest, if a RMT bot can be programmed to send 100 simultaneous tells to certain playes in a certain map every 5 minutes, then SE can program a countermeasure or at least detect this kind of comunication and stop it. I would have guessed with the cash shop at last they would have enough money to hire staff to be in charge of this, but apparently not. It is really not our job as players and customers to report RMT, keep track of our blacklist, and if that doesn't work, block tells and not being able to talk to our friends, it's SE's job.

Even a whisper to 10 different characters is enough to flag as bot. Who in the world as a person is going to select 10 different characters and spam messages?
