If I repeatedly send unwanted requests to thefacebook’s servers in ways they don’t authorize, and I ignore their requests to stop, their lawyers can sue me under https://en.m.wikipedia.org/wiki/Computer_Fraud_and_Abuse_Act
Example https://en.m.wikipedia.org/wiki/Facebook,_Inc._v._Power_Ventures,_Inc.

If Meta Platforms Inc sends advertisements to my ActivityPub servers even though I expressed no interest, and especially if my robots.txt or Actor URI indicates that sending advertisements is unauthorized, their lawyers should expect a cease and desist mentioning CFAA.

IANAL

But wouldn't *adding* posts/content to the "stream" effectively add it to the user? Something should be in the attributedTo field, and it would be straightforward to mute it if the field does not point to the user being followed.

(I'm not sure what would happen on Mastodon when the `cc` and `attributeTo` fields disagree, e.g. `cc` says `userA/followers` but `attributeTo` points something else, that would be interesting to check. What does the spec say?)

What is an ad?
    • 
If someone at Mastodon posts that they are hiring people (as they have), is that an ad?

This all is user behaviour. That other users can block/mute. I am thinking of META *adding* posts/content to the user stream, not the user themself. Remember that you subscribe to a feed/stream which gets curated by the instance. If that instance decides to inject additional content - is that part of the stream or not? Regardless of the content being ads or something else.
