When I load the all page, I get an alert that just says "1", which feels like it's probably a successful XSS attack. Given that, I can't justify putting my credit card number directly into the site. If it took Paypal, Apple Pay, or similar I would absolutely give it a try for a few months.
Screenshot of the alert (imgur marked it as nsfw because it includes a thumbnail of a post that is mildly nsfw): https://imgur.com/a/TmwO1jg
