Some of the "marketing purposes" that these dating profiles are used for include making it appear as if they "liked" you.
These profiles are not real and are used for marketing purposes.
From what we read in the terms and conditions page this site clearly admits to using make believe profiles AND the emails that these fake profiles send are "computer generated".
This coming directly from Nasty themselves, this is not something we are speculating, it is 100% proof that they are willingly using deceptive tricks against their own members.
They use the computer generated emails to lure you in, just like bait on a hook to snag a fish. When you reply to the email you are asked to upgrade and buy a membership.
If you bought the membership you took the bait and got duped, while the site administrators line their pockets with your money.
