My professional interest in the world of internet companies, domain/company names, and internet advertising means I like to see how a particular site is parked/squatted. (What ads do they think are related? Is there contact info for a domain purchas?)

I'm also not sure I'd trust Duck Duck Go and/or the crowdsourced 'useless'/'useful' rankings to keep up with site changes.

So on a browser with this, I'd always click 'proceed anyway', making this have negative value for me.
