may i ask how you know this
As some have feedback so are certainly NOT fake
Agree that at least one or two of the profiles could be genuine but having feedback does not mean not fake.
One of them has a feedback rating of 1 but has hidden all their feedback.
I'm sure they'll be more than a few profiles where fake feedback is done to get their rating up e.g. get a "friend" or whoever to create an account, make a booking on the system, then the users give each other feedback for the fabricated meeting.
For example, if you see a profile where they've got at least a few feedbacks but they are all or nearly all from people who have ratings of just 1 or 2 and all use similar language, these are examples of things to watch out for.
