Anti-spyware group COAST gave up the ghost after a messy internecine battle between members that would have liked to see adware firms reform to a set of best practices - distinguishing themselves from spyware - and a contingent that would rather have seen the whole lot of them suffer painful deaths at the hands of an enraged internet public.

The Consortium of Anti-Spyware Technology Vendors didn't survive the induction of adware firms. 180Solutions joined after the group developed a set of best practices to which firms could adapt.

This angered founding member Webroot Software, and precipitated a zipper effect of anti-spyware software vendors leaving the group. Anti-spyware vendors wares nowadays - perhaps in part due to intense competition to be the most complete - tend to root out spyware, adware, and even tracking cookies from syndicated research firms and third party ad servers.
