Wendy has simps going back 15 years. I'm sure she is doing the tip for a reward system because you can't request a refund when they didn't actually buy the content. She also isn't listing specific benefits for different tiers so she doesn't really have to deliver anything. She can set any price and her simps will pay if no one else will. She will probably cash out and close up soon. She will make some excuse about how people were too rude or leakers ruined it for everyone but it was likely her plan from the start
