The funny thing about people using #twitter #crossposters, or just still being very active on twitter, is that they'll post something here that includes the text of a tweet with a link to the original tweet.. and I'll click the link, and see a #mastodon user in their bio, and sure enough, that same post that they essentially cut & pasted from twitter is also on mastodon in original form. They could've just boosted it (or, if we had functional QTs, done that).
