9GAG Bot Zapper door Logosaurus

The add-on scans through your feed for any posts of known blacklisted bots and hides them.
The add-on DOES NOT gather any information from you or your browsing activity.

How it works:

-It receives blacklisted entries from a public gist.
-Saves blacklisted entries locally for quicker access
-Checks your feed, when browsing 9gag, for any blacklisted posts and removes them locally.

The add-on DOES NOT block users, it simply hides their posts from your feed, so you never have to see them.
