Even if they pull back on the age verification, the inference system is still there to judge every user by their posts and activity on the platform.
I've been trying to look for alternatives myself but none fulfills the needed use case yet.
- Revolt (or rather, Stoat) is apparently broken and still has very slow development.
- Root App is closed-source like Discord and is still under works. It only soft launched for public in light of Guilded's death. Apparently one can copy a Discord server's template to it and it'll carry over the role permissions.
- Element is the Matrix client I use but only for personal conversations. It may be too WhatsApp-y UI-wise.
- Session and SimpleX are also considered but might be too extreme for a common use case (and Session lacks perfect forward secrecy if anyone cares).
- I saw others like kloak.app and mezon but I don't know how trustworthy they are.
