I got that idea from how you seemed stressed about this. (Im too lazy to requote since I quoted it already) "So I just let them insult me because yes and they got away like that? Nice system you have over there"
If you didn't want them them to be punished or anything, you wouldn't have even said that.
About the contact thing. You don't seem to understand english well, so I'll say it using easier words. If you contact him, he can tell the people that are watching him to not make fun of you or to hate you, by doing this, some people can remember that you were still here and send mean posts to you.
Anyways, if you actually get to contact him, (He probably gets a whole lot of spam) what are you going to tell him? Are you going to ask him to punish the people that were mean to you? What are you planning to achieve from talking to him?
