I installed the official Reddit app and went on it to see what the old place was looking like now. My inbox was filled with spam. The "home feed" shows subs I never subscribed to. There are so many ads. Between the ads and the the extra subs in the feed, it's hard to just scroll. I also noted a lot of spam in some of the subs. Maybe they are subs with no mods? I'm not sure what's up with that.
You can usually appeal shadow-bans and they overturn them I’ve found, you have to send an appeal showing both that you know but also pretend you don’t know why otherwise they’ll think they owned you.
