I posted a text passage here, noticed belatedly that it had lost all its linebreaks in pasting, tried to edit them back in, and got an error “Body is too similar to what you recently posted.”
I assume that this is an antispam/antiflood measure that doesn’t differentiate whitespace, which is reasonable, but it seems like a bug to apply it when comparing a post to itself.
(I worked around by adding snarky commentary and then editing it out five minutes later.)
