well, look at the numbers. if you have 10,000 users on the site and even half of them (which i'm guessing is more, tbh) buy at minimum, a paid each month, that's 15,000 a month. then you have premium paids, people buying paids for multiple accounts, people gifting paids to multiple people (think of christmas anons gifting a handful of 2-6 months of paid time to randoms), and it adds up to enough to keep the site running.
