What I can't figure out is why people would put their real phone number in while registering anywhere. I mean, I always use the same number, it's a number that is not in use and that we cancelled about 5 years ago. I always remember it so it's a good one to use as a place holder for phone numbers. I never put age, and if required I have a date that has nothing to do with my birthday that I will put in. Why are people putting in actual real information?

I do not have a FB account but I use this formula for just about everything.
