Did anyone use Paymentwall?

I'm starting a new business in the social media niche, however as we all know most mainstream payment processors like paypal and stripe don't really like this niche, so it is not possible to get approved using them.

I've checked out paymentwall, and they seem to only prohibit things like illegal items, financial services and counterfeit goods. So I should be able to get approval in theory.

Did anyone have any experience using them, whether for a similar niche to mine or for a completely different niche?
