It appears to be a community where people post truly diabolical things that folks have done. Sometimes someone does something so annoying, so sinister, that all you can say is “well, we found satan.”
Perhaps because there’s enough explanation in the sidebar to figure it out and people want content, not questions. Also the OP is being a bit of a dipshit ITT and people may be downvoting him.
I tried giving a legit answer and look where it got me. OP is now so upset about getting downvotes that he has to find a way for something to be wrong with all of Lemmy in order to explain it.
I dunno, but I found a lot of people on Lemmy in the three days I've been here who downvote people for not already knowing everything, and for asking sincere questions due to it.
