Not that unusual. We had several mother and son, and father and son members in our clan, and other clans in UT99, and 2k4. Not the first time Ive seen someone get bitched at by a parent over what they posted etc. Same thing for in server stuff. I caught one of the kids swearing and spammin the server, and another one botting one day. The mom grounded her kid for swearing, and the other one was the dad. He took the computer off of his son for a week for botting and made his son apologize on the forums. Happens more than you might think.
