Years ago, Vercel scraped all the email addresses associated with my Github account and added them to their marketing lists. They still send me emails, with no unsubscribe option, because they insist I'm a customer. (I am not. Oxide, my employer, used Vercel.)

This should be illegal, but I'm in the US, so.

I've been musing on how to raise the cost of this behavior. My current leading contender: for each email I receive, generate 5-10 promising sounding leads using LLMs to engage their sales team and go nowhere.
