SpamCop and SiteAdvisor... working together.

I had an idea that I think would help people to stay away from 
spamvertised sites (and therefore, since most scams are spamvertised, to 
stay away from getting scammed for the most part, too).

I think by now, everyone's heard of SiteAdvisor.com... it's essentially a 
website reputation ranking service... they test websites for malicious 
behavior, and allow people to enter comments about websites that can be 
taken into consideration when ranking that site. There is a Firefox 
extension and an Internet Explorer BHO that colors search engine results 
green, yellow, or red based upon that domain's reputation, and a button 
with the same colors to warn people if they're surfing a malicious domain.

My idea entails SiteAdvisor.com getting a data feed from SpamCop. All the 
domains reported to SpamCop would automatically receive a "This site 
spams" rating in SiteAdvisor for 48 hours after the last reported spam for 
that domain. After that, the "This site spams" rating derived from the 
SpamCop reports would be removed for that domain (thus, when the spammers 
abandon a domain, someone else can purchase that domain and not inherit 
it's past spamming history).

User comments on the SiteAdvisor.com website about a domain would be 
permanent, however.

Comments, suggestions, etc.?
