WDYM Libadwaita is not customizable? Libadwaita is the most customizable UI lib I would say. You literally can just change every part of any app through css and call it a day.
I haven’t tried doing it in a while, but I remember it being very difficult to change themes beyond tint and colors, with lots of apps having custom colors not in the pallet used in the “gtk.css” file.



There’s a popular frontend for Lemmy called “Tesseract”. About a week ago the dev pushed an apparently malicious update with a block list which contains lots of leftist (as in even slightly left leaning) communities and users.
OP searched for and found his username in that block list.
The file OP searched in is “policy.json”, which doesn’t exist in the source code. The command pulls the content of the url decodes it from base64, unzips it and puts the content in policy.json. Which means the source code obfuscates the file by default.
(the only file called “policy” I could find in the source code is a .dat file which has the encoded data).
