There's a browser extension called uBlacklist, I use it to block all the main social media sites and anyone else who annoys me.

Reddit is banning everyone

This business of Reddit posts/comments coming up in search is very troubling; a while ago, I was searching for some medical info (on a condition I have and know a fair bit about), and some Reddit things came up so I looked at them for the hell of it. The first thing I read was just completely wrong. Like, totally wrong. I would hope people are being very leery of what they see on reddit, but they probably aren’t. 😕

Reddit is dying. Fortunately the fediverse is nearing critical mass such that every time you visit there is hundreds of new posts to sift through.

You could add something like -site:reddit.com to your search query, or alternatively use a search engine like Kagi which allows you to block sites from all future queries.

I believe uBlock Origin is also able to do this, but I'm not sure that is possible to use on iOS (I don't have an iPhone).

Same happened to me like a year ago, they wont appeal it
