Yes, we do. A number of instances have blacklisted bofa.lol, which is where this whole attack on Wheaton began.

I suspect that eventually the Fediverse will be divided into two major sections: places that are okay with "pissing people off" as a source of fun, and places that require basic adult civility at the price of, say, restricting your freedom to call an absolute stranger something vile.

I dunno how well the former will survive with read-only access to the latter. I would not be sad to see it wither and die, though several decades of life on the Internet suggests that's all too unlikely to happen.
