With a list of names, billing addresses, email addresses, telephone numbers, IP addresses (sounds like it's a list since the user first started to use LP) along with URLs having a 99.9% probability of the individual having an account at the URL... that can be pretty much catastrophic. Create a list of OnlyFans subscribers, or if there is a subdomain used for OF creators you can compile a list of them. Any service that uses unique subdomains (like the users username) means you can connect usernames with individuals and so on.
