I've been a member of this site for MANY years and have NEVER had a problem with ANY of those four ratings issues! Its lower ratings may be due to other fakes sites that can't compete with its quantity and scope.
This website has been around for a long time. It's perfectly safe. I know the owner personally, and he's a legit guy who takes his site seriously. It's not for kids though. Duh.
This has some of the most extensive collections of celebrity fakes I've found, provides information on how many there are of each celebrity, allows easy movement from one fake to the next in a list and offers a facility for grading fakes as well as writing comments on them. Some well-known fakers like Radir have provided a lot of work. I see no reason why it should be blacklisted.
