So I really don't want to be anyone's mom here, but I do also know a lot of people around here are quite young (or at the very least underage) and might not have gotten the same internet safety speals people my age did in elementary school.
Using your real full name or first name plus initials is always a bad idea. Using your first name is okay if you're really attached to it, but anyone who gives out more than that will be asked to change it. Obviously I can't force you to change your display name and there will be no repercussions if you ignore me, but the request will be made.
From here on out, anyone who posts pictures of themself will recieve an official warning. I don't care if the picture is actually you and will not take any steps to verify it. If you post a picture of a real person and claim it is you, that's enough for the warning. You all need to take basic steps to protect yourself.
