RuneScape.

RuneScape is a massive media online role-playing game. You can level up your person so you can be the best. You start off in this cave and you have to get past the tutorial. You start off at level 3.
It used to be only for 13+ but now its for everybody, because they just recently added the QuickQhat feature. QuickChat allows young kids that are not allowed to chat, chat. You select words from a list to ensure that your kids dont write offensive language.
Also, if someone wrote a somewhat offensive word like suck, it would appear like this: ****, because to some people its offensive. Also, you can report someone for bugging you using auto-typer (says stuff that you type in over and over again), and for following you when you asked to stop. OR! (This is a big caution to kids at a young age!) If someone spells an offensive word virtically it wont be blocked so you could say:
S
U
C
K
And not have it blocked, but thats what the "Report Abuse" is for.
