Totally agree, I did not consent to receive marketing for your start-up. My email is on GitHub for serious inquiries or security concerns regarding my projects.

I've recently starting calling out such companies. A couple of cases:

- Diffgram - Questioned how they received my marketing consent on their community slack chat, along with another user, got banned. - Buildable - Called out the founder on Twitter and was blocked in response.

While calling out seems just to result in being silenced/blocked, my hope is that it puts pressure on those companies, and others observing, to not market in this way.
