i Wonder how person below got hacked

Hey man, there is a guy on a Youtube who's giving CSGO and TF2 items for free. He donates to everyone, and hes still online. You can ask him for items but the bad thing is, you can get the items only once for free, and then you can't get the items for free. Link of the video https://www.youtube.com/watch?v=TmM1iZR1-zw
