Well, officially when someone quotetoots, and you look at that post from a vanilla server without QT, you'd see it ending in:
QT: -linkhere-
But with the latest Mastodon version, the link seems to be completely stripped off now, meaning that the posts get modified. Looks like Eugen is making his own ActivityPub standards now this way. Nasty... that's even worse than wanting a QT feature as your contents got modified.
