if someone that you know online hurts you - someone who you consider a friend or who considers you a friend - then tell them

tell them that you're hurt and ask them to change their behavior - or tell them that you need space from them

but /communicate/ with them, because chances are that they don't even know they hurt you

do not:

1) ghost them and leave them wondering where you went and why you're ignoring them

2) post vague messages about someone who hurt you and expect the person to realize you're talking about them (they won't)

3) blow up at them, particularly over something unrelated to the real problem

all of the above have happened to me at various times, and maybe I'm just a clueless jerk, but I had no idea that there was even a problem until the person chose those methods over productive, authentic communication

if you feel awful around a particular friend, for whatever reason, you need to talk to them about it and find a solution, whether that be working with them to fix the problem or leaving them altogether

don't sit on it and expect it to magically get better, because it won't

please communicate with people

(this applies to real life as well, but I'm specifically talking about online friendships, where we lack certain aspects of communication like body language and tone of voice and thus rely even more on the words themselves)
