Dumb@$$ staff and MySpace

I have had enough! I have a collegue who is intentionally provoking me to squash the internet usage within my office by openly posting ways around my (weak) web filter on MySpace. I think I will install a program that gives an allotted amount of internet time per day and then waves bye-bye as it shuts it off until the next day. On second thought, I think I will unistall her IE7 and take away the admin rights to reinstall it. Maybe I will only giver her access to three sites: Techrepublic (which is WAY over her head), ESPN (Which is WAY over her head), or the opening page of Disney. What do you think? Anyone else being taunted?
