WADS is a port of my World of Warcraft mod, now deprecated, to work in Wildstar, with some bugs fixed along the way.
Type /wads for a list of how it works. Here's the quick version:
A gold seller / guild recruitment spammer has the same string in all of their messages - www.gold.com for example.
Type /wads add www.gold.com
It'll be blocked from then on - if you don't want to see WADS tell you about it, type /wads verbosity 0
Let me know if there's any issues - I'll update the mod when I can (hopefully with a UI, etc.)
