I wouldn't say this is necessarily a good thing, this means you might not see messages from strangers who are trying to message you. damus would consider this way too much of a decision for a client to be making for you. but if people are happy with that then okay!

I could add a checkbox to disable that filter in settings. On paid relays it's probably fine without it. And for DMs I could add a limited list for requests from strangers, although it's vulnerable to spam.
Without the ability to flip it off, completely agree. Sane defaults with user control.
