I’ve become massively hardened to online discourse. I don’t need to block users when I can just ignore and not need to get the last word in. I know this is an incredibly rare ability, but I just wanted to entertain the idea here that there are alternatives.

The exception could be for discoverability. If garbage trolling spam overwhelms your front page, then it’ll be too time consuming to wade through it… So blocking entire communities makes a lot of sense in this case.
