I'm a sensitive person by nature towards myself and other people, however I do realize that people on the internet feel emboldened to do harassment against others because they're anonymous. The best solution is to either ignore them, or like you had done, move to another DC and if you desire to still socialize with people, find people who are willing to accept you and generally be chill. If someone doesn't mesh well with you, it's fine. Just cut that person out of your life and appreciate the people who appreciate you, but don't form an echo chamber. That is bad, and will eventually result in either toxic behavior or blacklisting people who don't agree with you over minor things. That's one of the only ways you can find some sort of solace, this goes for in-game and irl.

As far as blocking people to the point of filling up your blacklist... I am a bit bewildered how you got 200 people in your blacklist, if you were harassed by 200 people, I genuinely feel bad for you and I hope you're doing better now that you switched DCs. Wishing the best for you ^.^
