As an add-on developer, have you ever been the target of a scam? Today I received an email from someone stating that my add-on automatically charged their credit card account. The add-on they referenced is free, and doesn't collect user information or credit card information. I just checked my PayPal account, and no one has been charged. My payment systems don't ever automatically charge anyone. I don't use subscription services. So, this person is either a scam artist or an idiot.
