I’ve seen some people deal with newsletters they signed up for that way and it’s unarguably a misuse and abuse of the system. “I don’t want these messages any longer” is not the same as unsolicited or abusive mail. For instance I see a small chocolate company and a granola company in my spam folder in gmail. Do they “spam”? No, there’s a really huge difference between e-mail marketing and spam. It sounds like what you 'perceive' as spam is based on not really knowing what it is.

Poison all the data

Is that some juvenile badassery or something?

fuck spammers straight to hell, tyvm.

yes, fuck spammers but not small companies doing email marketing. Email marketing is the only effective way to grow a business online these days without paying some giant fuckstick corporation like Facebook, so I don't believe what you stated is accomplishing what seems to be your goal. If you make email marketing unusable, that helps google sell ads.
