Did you have backups set up for your mint installation? Depending on how long its been, restoring via timeshift might be worth a shot. I'm relatively new to Linux so idk if that could fix it.
I'm sorry but I've had a very different experience on rednote while browsing the #Lgbt tag.
I've seen at least 3 different posts ::: spoiler CW: anti-trans Complaining about a billion genders, children getting "groomed" into being gay or trans, drag queens brainwashing children in schools, etc. :::
There's some very positive and informed content on the app as well, but it's not all sunshine and rainbows by a long shot.
Edit: I can't post the link but just take a look around the #lgbt tag
I like the customization options for Searx, but I had to eventually switch back to Duckduckgo/Startpage. Sometimes an engine would start timing out or requesting captchas, or an instance would go down and I'd have to add a new one to my firefox desktop/mobile, or I'd notice that the results I got through an instance via one engine or another would be very different from the same search ran on said engine directly. I feel bad, but I just don't have the time or patience for it.
Nox has a lot of great stuff on his yt channel. One of my favorite animator/producers.
Animal Well, UFO 50, and Balatro in that order.
