Blacklist with auto-downvoting for Reddit. For those special trolls..
TrollAway is a reddit blacklisting extension for google chrome.
It allows you to selectively add reddit users to a blacklist, which is then used to auto-downvote any future comments that user makes on a page you happen to visit.
The interface is super simple.
A "blacklist" link is added underneath every comment.
Just fire and forget.
Any future comments that you see will be checked against your blacklist.
If the user is in them, the comment is downvoted.
