Any experience with Selly/Rocketr/Hexpay?

Basically I'm wondering what people's opinions are with Selly, Rocketr and Hexpay. So far all I've heard is that those platforms are full of scammers, especially if you're buying things. What I'm wondering however how safe/well it works to sell products on it. I've considered accepting donations through those platforms for Sythe, but I'm not yet sure how that'd work and if'd work properly. Anyone who can provide me with some info?

Yeah figured as much, most claim it's a website full of scammers etc but I guess that aslong as I can confirm my identity on Sythe there's nothing they can be afraid for. I'm just wondering if it works well in a sellers perspective. And.. if it's easy to chargeback payments via there, such as if someone buys through Paypal there.
