two things.. officially yoshi-p replied a question asked by a top gaming site interviewer (Google yoshi-p parser official) and he said that as long as you don't use it to harass others/talk admit it in game they won't hunt you down.

secondly, this is the internet. you need report them using the gm tool under support. complaining here isn't really saying anything except "look at me and how little I'm willing to do proactively" .. this is the internet. people can and will troll and harass you. not saying it's ok, but the people who are doing it will unlikely be seeing this post.

good luck to you!
