An even worse form of such practices are sites that basically crawl yelp or yellowpages and then proceed to spam and call small businesses with the lure of 'claim your profile and get customers', when all it really is just emails from unqualified people submitting their contact information through the main site and randomly getting matched.

This startup company has ton of bad consumer reports, I'm glad that I ended up not working on their website. I would've had trouble sleeping had I seen what their website was actually doing, ripping off small businesses with fake leads.
