Paypal, Ko-Fi, and all these other websites are tracking you through the links you click and the cookies you pick up along the way.

They then gather that information, analyze it and then use that to inform them as to which accounts to nuke. As an example, if you post a ko-fi link directly on baraag or pomf, then they look into the site and discover the content there, they can use that to kill your account even if you posted nothing but the link.
