You will need to install a user script manager extension to install this script.
Got fed up with e-girls spamming and selling content finally. Wrote this little script to block users who have "onlyfans" and a few other keywords I could think of in their profile field. It's set to trigger every 5 seconds (best way I could come up with to work with RES's NeverEndingReddit feature) but it tries to be polite by marking every post it's looked at already.
If there's someone you like despite them being a seller, you can add them to the exceptionsList.
