The Signal messenger and protocol.

For the past 4 days or so, I’ve received around 5 message requests from random accounts and was added to 2 groups with other random people. I assume these are fake accounts and scams.

Was my number leaked somewhere maybe? And even then, why use SignaI? I don’t really have a lot of contacts on Signal, mostly just family and a couple of acquaintances who also have it. And I’ve never gotten a random request in the 8+ years I’ve been using it.
