@tallship In your example, all you'd have to do is block the ex-girlfriend on Signal. Furthermore, unless you accept her initial conversation request, she wouldn't be able to access any profile information of yours (profile name, picture, bio, etc.).

I'm looking forward to usernames and phone number as well. Hopefully, the team would be able to focus more on this after stories are out.

BTW, some instances have a higher character count limit if you're into long posts.
