So, this meme.
tl;dr Mastodon users occasionally spam mentions and Lemmy (and probably Piefed) ingests them all and makes the post across all of the mentioned communities.
Sucks, right, because on the theadiverse, you’re not actually able to do that so easily.
Basically, it’s because Mastodon mixes mentions with addressing. Every mentioned person gets addressed, even though sometimes you don’t mean for it to go into that community.
So what if Lemmy, Piefed, Mbin, and NodeBB made it so that only the first matching community gets the post? We can already tell which posts come from threadiverse software and which don’t (because we use audience, Mastodon doesn’t.)
Just an idea, I can’t speak for the other softwares.


[email protected] isn’t wrong though, in many cases the posts do mean to be posted in that community.
But it’s an expressive thing. I’m able to mention a community like [email protected] and it won’t be posted there, because I’m only mentioning that community.
And yes, Mastodon needs mention spam to function because otherwise people you reply to won’t know they received a reply. It’s … an approach.
