help dealing with harassment

[Jin-]

Only way to truly be hidden is to get a new account. No matter how many times you change your name / change servers you can be found.

I don't know you OP but maxing out blacklist so quick is strange to be honest. My friend told me that people are bad and they already filled the blacklist in few weeks after starting the game. I know in their case the problem really isn't the people being bad.
Maybe it's similar in your case? Being too easily offended or reacting negatively to everything?

I am sorry it's happening to you.
