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.
Those huge default subs are virtually impossible to comment in. Automods delete any posts that don't conform to twenty different parameters. It's maddening.
Explains how bots are the only activity in them, because they've been programmed to conform to posting rules that no human can possibly comply with.
