Differences with cleek's filter include:
- You can block and unblock commenters with a link attached to each post
- No pie, just a very skinny "trolling by Trolly McTrollson" sort of header.
- Blocked posts can be revealed by clicking on the header
- Replies to trolls are completely filtered (not just quotes)
Update 2013-05-15: I've updated the script to work with BJ's new look. GreaseMonkey and TamperMonkey are supposed to auto-update, but that doesn't always seem to be the case, so click here or on the script link to get the latest version. And for more BJ action, the filter looks best with the Better Balloon Juice stylesheet applied.
Update 2013-05-19: The script is now hosted on userscripts.org, which among other things, has install instructions for making the script work on lots of different browsers (I've only tested it on Firefox and Chrome though). If you already have the script installed, I recommend removing it and reinstalling it from userscripts.org instead (the links in this post are updated, so just click on them).
