No, I think bobdvb has a point, and mostly where I think I'm going with this is that abusers should just be shut down. In the context of FOSS, I think that means some combination of a) don't tolerate their attacks and b) shut them out. Whatever that might look like, basically it just deprives them of using your project as a platform to satisfy their perverse interests in making someone feel miserable.

So, I'd rather not frame it as "abuse the abusers," because I think that risks escalating the situation.

Five years ago I may have agreed with you, but a lot has changed in my life to recognize that it's just not worth the time trying to engage someone who enjoys being mean.
