[Wikipedia-l] protected pages

[Ilyanep]

I'm a sysop, and I don't want people messing up certain pages under my user
page...would it be considered unfair if I protect them or am I allowed to do
so?

The reason I'm asking this is that I have a few friends who I want to see my
'article' under my user page and they're all anon's on wikipedia, and
there's a big chance that they'll mess it up and leave (never wanting to
come back so blocking isn't an option!)

I could just tell them to stop, but I'd feel much more comfortable with the
protection on it :)
