Going back to the old BBS days gone past... I had done up a super-awesome Renegade BBS theme, menus, etc. Well I showed them to a kid and he used them for his own BBS. I was pissed, and believe me, my plan took weeks. I was able to convince the kid to make me a co-sysop on his BBS, so I could "help out" with maintenance and things. Set an alarm one night for 2 or 3 am, so everyone was sure to be asleep at his house. I logged on, shelled out to DOS and did the ol' FORMAT C: /U. At any rate, he got in huge trouble, since all his parent's financial and business stuff was on that same computer. I never got found out, but felt really bad afterwards. Nowadays, I have to laugh a little about it.
