I had some business reasons to have an account and participate in a few niche subs. The subs were niche enough to mostly be enthusiastic friendly people, but it didn't take long to notice the patterns of the same ideas making the rounds.
Then one of my posts was removed for reasons I don't understand (and didn't try). Whatever the mod was thinking, I just gave up, deleted my historical posts and removed my account. Not worth the effort.
Up to that point, old.reddit.com was working (with or without signing in, mobile or desktop) despite the threat to shut that down. I wouldn't use the new interface unless you paid me a decent wage to do so.
I've quit Reddit before - it's very toxic overall - but now it's not even worth it for business. I doubt they'll ever lure me back again.
