Apparently, I have blocked users that I am not even aware of, so it would be nice feature to be able to check to see what you may have inadvertently blocked.

I just happened to notice on a submission I made, and had to go as unauthenticated to see why I could not see certain comments, and apparently I had blocked someone erroneously ?

I didn't see any other method to accomplish this, unless I am missing this features location.
