/cgl/ - Cosplay & EGL

So, I would like some tips on how you deal with toxic people inside your hobby, be it Cosplay or JFashion.

By toxic I mean people who are always looking for ways of stirring up more drama, talking about people behind their backs, making fuss over irrelevant things to keep relevant and being randomly mean with people for no apparent reason.

I don't want names or shame, just want some tips on how to deal with these people, specially if they're in your comm.

Do you openly talk with the person?
Do you ignore him/her?
Does your comm have any guideline on how to deal with them?

Thanks in advance,
