When I see a site that attempts to stalk me (even if my countermeasures manage to block it) the last thing I would do is to hand them my personal and billing details on a platter, give them money, and act as a "manual" tracking cookie by logging into my account every time I visit the website (to bypass the paywall).

At least beforehand the best they could do is to get pseudonymous network & browser data (if they managed to get past my countermeasures like uBlock and nasty IP ranges blocked at the network level), where as once I pay they now have confirmed billing details they can do whatever they want with. If they don't respect my privacy before I pay then I have no reason to trust they'll suddenly respect it after I pay. Most likely they'll just attempt to have their cake and eat it, aka take my money and still stalk me.
