That's interesting. Would your use of these sites be affected if you had to submit your ID to use the site (other users wouldn't know who you are, but the site and possibly forum admins may know or be able to find out).

Not original commenter, but I would opt not to use such social media. There is world outside of computer, less social media is less temptetion to waste time online :)

No OP. I wouldn’t use social media sites if they require my ID. It’s just not worth it.

If I had an account there I would not post anything ever. Even Facebook with real name policy which I obeyed, basically gets maybe one post from me every few years because it feels too dangerous to get people pissed at my primary identity. And people can get pissed at you for explaining science to them.
