If people are being rude, here is my advice for you:
A) You can use /ignore so block their messages, or you could just “agree” with people when they’re rude. It usually works for me, and it doesn’t cause problems most of the time.
B) Report them. You can upload screenshots of it on imgur.com.
C) Try to befriend them, it might work. If they keep being rude, try option A or B.
