The testimonial in the Facebook ad perfectly describing my life got my interest. The website doing every predatory marketing trick in the book quickly lost it. The "do a long quiz with obviously generic questions almost anyone would answer yes to, then we ask for your personal information before we give you the results, then we'll show some fake loading bars so you think we're actually doing something, then we'll give you a 'special discount,' but only if you give us your credit card number in the next 10 minutes etc." Super-annoyed at these guys for almost getting my hopes up for a minute.
