@jackemledsignal can be pseudonymous, with caveats:- don't share your number, set a handle and share that- set a generic profile photo that could be SFW or NSFW (not tied to anything)- set a bio that doesn't out you- disable notifying people you joined by phone number (it helpfully uses their contacts, not your contacts, and isn't consent-respecting by design, and could out you)current limitations:- group stuff: @signalapp doesn't have a feature to let you delete mass spam messages from a user as an admin. very weird. you can appoint admins and block people though. user forum hostile to mod concerns.- thread stuff: signal doesn't have threads/rooms, you'd need to be in multiple named groups for this- sticker adoption low
