It's kinda useless. All it does is blur the submission; it doesn't remove the thing from your searches, it doesn't discriminate with other things you may be ok with, and... worst of all, the change to the site made it so that the "Filteraffinity" browser extension no longer works, so you can't even filter out USERS you don't like any more! It is TOTALLY broken...

also, they completely dropped the ball on one thing the site STILL needs: Not showing you submissions from users you blocked! The only thing the "Block user" button does is make it so that that user can't message you or reply to your comments. It's pretty much useless if they ALREADY don't do that.
