I think I received a ton of these from Photobucket, where I didn’t even know I had an account, for a whole year before it finally stopped. September 2023-August 2024, I just checked. The thing was, they were asking me if my account could be deleted but required me to log in to the account and I didn’t care enough to bother with a password reset and all that.

So for a 6 month period they sent a new mail every 3 days. I honestly thought they were never going to delete the account, but apparently they did eventually.
