It is very easy to manipulate their so called 'Reputation Scorecard'. I have no 'trust' in a company that is so easy to manipulate ratings with.
Nice, Web of Trust can kiss my ass. Anyone can write anything they want on there. I am also a pimp and a nuclear scientist.
When I was looking into this sort of market (website trust metrics/scam+spam defense) WoT was the biggest player but their accuracy was absolutely horrible which made it near useless.
How they get their data is by relying on their community without any sort of trusted review process. This is cheap (almost free) but yields the kind of crappy results WoT has.
Combine these two and I can't imagine this is much of a company. It may have been at one point but if it was it was probably gutted long ago and is just lumbering along in zombie mode now.
I really believe this is a space that is ripe for someone to come along and do it right.
(Disclaimer: I have no idea what their current situation actually is, this is just my speculation from a cursory review of them a good 6-8 months ago.)
