I know this because I use SimpleLogin to provide each service with its own specialized email address. You can see in the picture the address starts with bixi@sl.***
It’s also possible but unlikely that they sold user data.
This is not sufficient for your conclusion given the burden of proof required for this claim. And, to be clear, you are claiming that: This organization controlled by the municipality is SELLING your email address. Your proof is a screenshot with the addressed censored. Not that there was a leak, not that someone guessed this handle, not that PBSC got hacked, not that you typed the wrong handle into a form. I can run this past bixi for you if you DM me your address, but you’re assuming a lot and I would bet not just MAGA but real coins that you’re wrong about bixi selling your info.
Btw I contacted them by email this morning and gave them all the information I have, waiting on a reply.
I sent you a PM with the information, let me know if you got it :)
