Userstyles.org just doesn't work
Everything takes like 5 minutes to load. Stylus extension always returns Error 0 while trying to get new styles simply because userstyles.org fails to load. I couldn't even attach a file while creating this discussion because of 'Internal error, could not move the file.' Fix it already.

There's not gonna be any fixes, site is abandoned long time ago. Current owner is SimilarWeb, analytics company. They only want to collect data via Stylish addon, there's no interest for them to fix the site, because it costs time and money for nothing to gain.
