I never used it much, lurked. Definitely swiped a meme or two from there.
Wasn't a big fan of how clunky and JS dependent the site was, and how little these 'alternative reddit' type sites did little to protect end-user privacy. Pretty much what I said could be applied to the same question if it was about Voat, but Voat had a better interface. Two sites I had accounts on but rarely logged into.
I had one reaction banned for saying 'jews are arabs'. Since then I left ruqqus, which now is no more.

Worst: Thinking that it would at least be a refuge after Voat died. I was wrong.
Best: Being banned by the leftist moderation, proving everything I’d come to think about it after using it.
