My 16 year old brother is on a boot camp. Our father decided to send him there as he was addicted to online games, which my family have nothing against to, but he used to play the whole night, even on school days. The day before he left, my father deleted all the games. Somehow he took his computer to the camp. The camp staff said it was okay, they had no internet access. It seems there was and some in-game friends told my dad he was in the computer downloading the games. As we have different computers, is there a way for me to see if he is actually playing? If he is using my dad's credit card (which is saved in the computer to buy game money). I've posted the some question in other forum and people suggested many kinds such as keylogger,parental control software, remote desktop spy and many more.
I need some creative, yet EASY suggestions for which would only let us know if he is actually playing, so we do something about him. We want him to change. Thank you.
