There's always a negativity bias in reviews. People are more likely to go out and leave a bad review than they're likely to leave a good review for service as expected. That's true for any product or service, and it's something you should always take into account when comparing stuff online. You're incredibly unlikely to find a product with only real, positive reviews.

Based on their apparent automatic abuse filter for new customers (probably filtering out known scammers or something) I'm willing to believe that some people are blocked from the platform because of false positives. I'm sure some of those complaints are real and valid, but I'm also sure you can probably work your way through the block by providing them with some more PII to verify your identity if you really want to become their customer.
