@Gargron Just to raise a question, as I don't know enough about the technical aspects even to speculate properly. Possible for "disallow quotes" be retroactive? If the option is on & a post goes unexpectedly out of control, could users have the option to make the quote-posts vanish? Maybe not as effective as just deleting & maybe overly complicated. Not sure. This is just brainstorming. But it's often incredibly difficult to predict what goes viral--or even a few steps in that direction.
