I'm a Patreon user, and I got the scam email.
They claimed "I have your tax id, tax forms, SSN, DOB, Name, Address, Credit card details and more sensitive data..."
All Patreon has of mine is my credit card info, name, and billing address. The same stuff any online retailer, or anyone who takes payment has. They DO NOT have my tax id, etc.
So it's obviously a scam right from the beginning.
