Some people have wild personal psychologies.
All I really do is post owl stuff, and I'll pick up a stray downvote here or there by accident I'm assuming. But I had one user downvoting near every post I made. No biggie to me, just a curiosity really. I wasn't sure why they wouldn't just block me or the community if they didn't like the content, but whatever. This went on for a couple months.
One day they left a comment finally and it was a positive one. I replied essentially "thanks, but I thought you hated my content or me myself." Their reply was "nah, I love all your posts, I just downvote everything from .world to lower them in the sort." My guy, it's one vote. The whole thing was funny, especially since learning they were actually a fan, but so confusing to attempt to penalize someone for such a random reason, especially someone you seemingly enjoy.
