If you see someone on mastodon.social using a cross-poster from Twitter and never actually posting/responding here, please report them. I think that can be reasonably considered spam.
@Gargron I'm using crossposter in both directions, but I notice that I'm using Mastodon more an more, as more people come here from Tumblr. And with 250 symbols on Twitter against 500 or more on Mastodon, surely I prefer to write here
Exclusive or something
