I worked IT in a high school for about 10 years. Here are some of the doozies:

• weed stashed in a PC case
• pop tart jammed into a DVD drive
• illicit domain admin account created by a student worker
• script to set porn to be the default background on reboot.

I’m still getting used to the whole “instance” thing but I think that a FOSS, decentralized thing has a better chance to stick around a while.
