LOL one time I came across a reply I found interesting, but I couldn't see the original post. Turns out, the OP was somebody I'd blocked, but I'd forgotten why. Turns out, he was posting antisemitic conspiracy theories, and images with nudity.
Moral of the story: if I block only content I am unwilling to tolerate (porn, nudity, and obnoxious racism), remember I blocked all the people I blocked for a reason, and leave them alone.
