I contacted the customer support for all of them and they said they can't do anything about it. To change the customer's e-mail address, I need to prove I'm the customer, and obviously I have no idea who they are.
So I gave up and implemented a Gmail filter in the end, but I definitely wish that parallel with the traditional unsubscribe, there was a way to say "this isn't that person's e-mail". Where I don't have to prove I'm the person, I just have to demonstrate I receive the e-mails.
I have in the past had very good data on how often a russian guy got a haircut.
I've also done this where I've donated $25 to U of California in the name of my friend who went to Stanford (rival universities). He's likely still getting calls.
> whenever I don't feel like putting my own email or phone number I just put his
This sounds more like malice than well thought out humor. If I found out someone I knew and respected was using my primary contact information for spam emails at <insert random pet supply store or random restaurants' rewards programs here> I would definitely consider not talking to that person much any more. The rival university one however I would let slide because the intent from you is obviously different.
Have you tried doing this recently? Creating an email address has become a fairly draconian process.
I'm not sure, are you implying that it is not worth doing this, and you would rather instead just pollute the inboxes of people that happen to know you? If so, would you like to be friends? I'd be happy to receive your junk emails if in exchange I can come by your place and just leave my trash in your front yard/driveway.
If you want an account for random garbage that demands an email address, use mailinator.
I'm not sending these.
Hostile? A bit, but after contacting services and complaining, nothing would get done anyway.
I ended up changing email providers because of that.
