Start by reporting bugs is a good start even for those who don’t know programing, for developers many project have documentation usually on CONTRIBUTING.md or at the README.md itself, includes code of conduct, Pull Requests, Bug Reports etc…
Example for Lemmy https://github.com/LemmyNet/lemmy/blob/main/CONTRIBUTING.md
Is just a link to docs
Here’s a better example: https://github.com/honestbleeps/Reddit-Enhancement-Suite/blob/master/CONTRIBUTING.md
ImgurViewer, works with Imgur and many other sites.
GooglePlay: https://play.google.com/store/apps/details?id=com.ensoft.imgurviewer
F-Droid: https://f-droid.org/packages/com.ensoft.imgurviewer/
Homepage: https://github.com/SpartanJ/ImgurViewer
I use it for some years, opens almost everything that’s not supported by some apps.
Just one thing, must be indefinitely not 48h, otherwise nothing will change. A year have 365 days, 48h it’s a weekend, if subreddits come back after 48h it’s nothing happened.
There are some forks trying to make that easier, like this one https://github.com/KhoalaS/Infinity-For-Reddit
