Hey, I agree that patreon should crack down on people who have abandoned their project and still collect money, there are certainly cash grabbers out there.
But the description Patreon gives about themselves would have helped you more
" Patreon is a monetization platform operated by Patreon, Inc., that provides business tools for content creators to run a subscription service and sell digital products. It helps artists and other creators earn a recurring income by providing rewards and perks to its subscribers. "
I run a subscription service, and with that subscription comes rewards. Some rewards are not handed out every month, and if someone is looking for a specific reward, they can pledge their support when it's available. There is no purchase, unless you count a discord rank as a purchase, but that's just an incentive to donate. I don't think anyone is out there saying "OHH FINALLY I CAN GET A PURPLE NAME IN RUNEY'S DISCORD!?"
