Hides anything related to karma on Old.Reddit.
I've always despised the "Karma" system on Reddit, and I wished there was a way to remove it completely. I looked around for scripts and I found several but none of them removed everything. So I decided to make my own based on one of them that was called "Hide Karma". I modified it to work with old Reddit and expanded to remove everything related to karma.
I did not test with the new Reddit because I hate it, and I tested it with Tampermonkey.
And now it hides more reddit crap (premium ad, header image, secret santa, awards, notifications...etc).
