Not sure if emails work the same way, but this is how phone scammers work

If you interact with a phone scammer, send them to hell or do anything at all with them, you just get added to a big lost of people that respond to scam calls and so you get more calls

It drives me nuts that I can't turn off the unsubscribe feature entirely. I'll use their unsubscribe button once, and if it doesn't work, then all future emails are getting forwarded back to whoever I gave the email address.
