I will offer you a really nice suggestion. Never, ever post items such as this. You are waving a bright red flag at CO. What do you have to gain? What you have to lose is for CO (or DL, AA, UA etc) to trace you (and some people have their actual names in their email address profile etc) and extract the correct mileage. If you eventually get the guilt's, you can volunteerly deduct it.
Something refering to gifts and looking into horse's mouths comes to mind. I strongly suggest you totally delete your post. My mouth, as usual will remain sealed.
