What was your experience with a Mole? at work, daily life etc.?

Question

People make mistakes and things happen, but there must be a time in your life when you were Mole-d. Either you knew what happened or you just thought you knew, what did you do about it and how did you get over it? Did you Mole 'em back? If you did, how was it done and what was the result?
When I found out I was Mole-d, I left and started a new life. I didn't do anything to the Mole, knowing that one day a better Mole will mole the Mole hehehe but then again, this is just me...
