Can I abandon a Gmail address that’s getting too much porn?

IMB is receiving explicit emails and is thinking of creating a new account

Someone has been using my Gmail address to sign me up for things online, and I consistently get explicit emails sent to my inbox and my spam box. I have decided to get a new email address, abandon my current one and delete it from my phone account. What will happen to my old email address when I'm not using it? IMB

It's amazing how little progress we have made in the past 30-odd years. First, any company that still emails people - or adds them to mailing lists - without a "double opt-in" is run by idiots. If anyone signs up for anything, they should get an email that they must click to confirm they really want whatever it is. This remains true even for porn sites.
