How do I deal with online bullying and harassment from fake friends?

I ended up watching some crappy gamers and half of this people weren’t my real friends. They ended up being fake now some of those motherfuckers over a year later keep harrasing me? What do I do? I stopped watching half of this people and moved on to other streams but is the same bs and when I defend myself I am the bad one.
