The Salon Kill File was originally created by Salon user "Frankly, My Dear".
I stumbled upon it, modified to work with mobile.salon.com, added Favourites and added auto spam detection.
Tero (tech.nimbus.fi) then added a bit of clean up and supplied that back.
I merged in the changes, posted them into the download repository, and he promptly supplied me with a brand new, unrecognizable, 100 times (not percent) better tool - with buttons!
Once I wrapped my head around it all, I added CSS, a new button, auto-ban based on content, auto-downloading of banned-content, etc.

Added Opera support. Simply required overloading GM_log = opera.postError, and borrowed a GM_addStyle() from a script at HowToCreate.co.uk, which may or may not have, in turn, come from ReifySoft.com. Copyright details in script source code...
