In one project I inherited, some contractors had been maintaining the code for about a year. Every change they made they added a comment box around it like "Mike made this change on Dec 31". What's worse was they included a copyright indication (I tried to find out if anyone had gotten a copyright assignment from them and the legal department literally slammed the door in my face). Their changes were bizarre and included a lot of things you ranted about. I reverted the code to the state before they arrived and sent the result to QA. "Wow! How did you fix so many bugs so quickly?" was the response from QA. We had an iron clad contract with that contracting firm, but after I started reverting every single subsequent change they made, they stopped sending changes ;-) Luckily my boss was a director and could pave the political fallout from my rather brash (but justified) actions.
