I tend to disagree.

I think the comparison to email spam is apt. The answer to that problem was automated spam filters.

Imagine the difficulty you might find interacting with the world if your inbox was set up such that all emails not literally written by a human were auto-deleted. No account recovery, no receipts, etc. Individuals might choose to do that for themselves but it's not the general case answer.

That's different though - those are services you explicitly agree to and sign up for, be it at checkout, be it at service signup time, be it because you are making a google account on the google platform.

For example, a github cicd automerge pipeline is still good.
