But what information is there in an account other than the posts? It’s not like facebook, where you have photos and other things that only certain people are supposed to be able to see.
By default, anything posted here is visible to the world. We have exceptions like the Temp and the Lounge, but anyone can join the site and gain access to those automatically by meeting the requirements of simple algorithms. (The invitation-only secret fora are another story. I mean, uh, if they exist. )
If you’ve revealed your real name and location in the public part of your profile, you can remove them.
