I find this to be less of a problem in less formal spaces. When typos, capitalization, and memes all get incorporated into the dialect, sarcasm and other nuance comes across much more readily. See also: Tumblr.

I suspect that sort of dialect wouldn't be as comprehensible here though, because of the greater diversity in demographics here than Tumblr or my small closed group chats with friends. Here on Lemmy, I try to mitigate this by giving the benefit of the doubt and never ever feeding the trolls.

(Does downvoting a troll count as feeding it, because it gives them attention? I don't want to risk it, so I usually pass them by, but I'm curious as to people's consensus here.)
