Fun fact: if you think you are going to pull one over on tech support, you are wrong. If you broke your shit, own up to it!
I talked to a dude recently who broke his server entirely. Completely his fault - he was f-ing with stuff he knew nothing about. He swore up and down he hadn't done anything to his server in "months", so I log in. The last login was on that day. I ask the guy what his IP is, and interestingly, the login came from that IP. So, I start looking around at command histories. Turns out that the history showed like 5 important files edited. This guy had no comment when I pointed that out. Hehe.
