Group block entire subreddit

My idea is to allow entire subreddits to be group blocked - where every user in the subreddit is blocked from your profile.

I’ve found that some subreddits are problematic in terms of their user base. I’d like the option to block every single member of a subreddit as a group. I don’t see why this should be a problem, it doesn’t impact those people in any way except they can’t interact with me. I get there’s a mute feature and I get that you can hide your profile comments from being public. But I want my profile to be inaccessible by a whole group.

Obviously you would also auto-unjoin such a subreddit with this action.
