I have the same problem and at least once a week someone tries to recover the password to “their” email address. I’ve gotten unlimited spam which my provider usually deals with well but sometimes there are periods of days where 5+ per hour get through. I’ve gotten dick pics and all kinds of receipts. I have hotel logins with the wrong name assigned because I could only make accounts by recovering one someone else made (so my hotel receipts have the wrong name on them).

I used to reply to misaddressed mail when it amused me. I used to string along a whole family of people that included me in group emails with racist Obama memes and pictures bragging of poaching.

I stopped replying to these when in another case I was asked to tell estranged and family member that their sister had cancer since I was the only one still in contact with her. I did inform them they had the wrong address at that point.

I’m still on a mailing list for senior members of a local police department and even was sent logon/passwords to some of their systems but I’ve learned not to try to correct these things, it’s just too much of a hassle. In the case of Venmo and Verizon I couldn’t get it fixed even with phone calls.
