I met someone who has a business there and he is legit, but as far as the reliability of the reviews there I wouldn't know. I'm afraid to even go on there. I did once out of curiosity a long time ago when they were launching a "Google for the dark web". I'm sure you can do some research and find out what the general consensus is.
We have had members who have asked me if our reviews are real, but I don't think I would be the person to ask if you were truly doubtful. If you spend some time reading, whether it's here or there, I think it's going to become apparent if they are fake.
