Ask HN: What to do about Non-CANSPAM compliant emails from YouTube?

As an individual, you have no rights under CAN-SPAM. I suppose you could file a complaint with the FTC and your state attorney general. Your state might also have an anti-spam law with more rights but CAN-SPAM pre-empted some of them.

File an arbitration case (assuming your bound by Google's arbitration clause) or file a small claims court case.

Many jurisdictions have increased small claims case limits to $20k.

Nothing. The government is toothless against the likes of Google. Filter it and move on.

Maybe you could try routing the emails through an account registered in a country with stronger anti-spam protections?

Make an email filter and move on. You can't put a stop to it.
