Ironically Signal is one of the only protocols that is even a little bit resistant to social graph attacks
It's definitely possibly for Signal to work around [sealed-sender](https://signal.org/blog/sealed-sender/) by analyzing the timing of traffic between various IP addresses over time to build a rough social graph but that's a lot more difficult to build and there's a lot less information available than, say centralized OMEMO XMPP like what WhatsApp is based on
(It should go without saying that Signal is doing exactly that and that their insistence on requiring phone numbers is in a large part an attempt at linking real-world data to those rough social graphs)
