This is precisely why personal use of workplace computer systems is prohibited. You may think you have the most boring job on the planet, and a little Facebook, web surfing and IM chat won't hurt to pass the time. The 5,400 people whose personal information has just been put at risk would strongly disagree.

If you want to act like an utter moron and carry on sharing shady links with your fake Canadian girlfriend, USE YOUR OWN PHONE. When it's infected or otherwise bricked, you'll only damage your own property. I can't even begin to say how many times I've seen employees of desk jobs in hospitality, medical or other office positions using their company computers this way...

Employees with routine access to systems of this nature are (I would certainly hope) counseled on day one that there are repercussions to violating common sense security policies. I fail to see how embarrassment helps to strengthen the apparent nonenforcement of these extremely important and basic guidelines.
