Nothing annoys this user more than when a teacher says that Wikipedia isn't reliable and that anybody can enter anything completely untrue that'll stay.
My main reasons for doing this come from the fact that schools teach that Wikipedia isn't a reliable source. I resolved to help make it reliable by stopping people from vandalizing it.
I know that Wikipedia is supposed to allow all people to edit, but I do tend to wish that all IP editors would have their edits treated as Pending review. I also think that any page whose topic matter is the subject of current controversy should be semi-protected until the controversy dies down.
