Remember that Reddit is essentially a glorified news aggregator that also allows memes and porn and has NFT avatars for some fucking reason.
As far as I know, adding the RSS feed of a subreddit will keep working as usual, unless spez gets wind of it and kills it too, so don't tell spez.
So, if you still need or want to read from a certain subreddit you can add /.rss at the end of the url. For example:
https://reddit.com/r/antiwork/.rss
I use newsboat on the desktop, because is a terminal based app and terminal based apps are BASED. There are many more fancy readers on desktop.
Also Feeder on mobile is pretty good, it's available on F-Droid.
With that and moving to lemmy you might break free of your reddit addiction and not fall into the trap of using the crappy official app just to watch dank memes.
Also forget about Karma. I have over 200K karma on Reddit that is utterly useless. Touching grass is more pleasing than getting karma. You can read something on reddit from your RSS feed while touching grass too, multitasking.
Sign up for a VPN. That should get you around the IP ban. Big providers like windscribe have lots of nodes you can use to change your ip address.
