Its a real shame that gaming has sunk so low - firstly just block and report (and maybe also show your son how to do it?) As many have said, your son will gain more from the 'there are good and bad people in the world' conversation that I'm sure you've had to have. I know my 10 year old son did and now knows how to treat Bullies, both online and in school. I tried to preserve and protect his 'childhood' for as long as possible, but with the online presence invading our lives more and more these days, its a conversation that is better done using an event such as this. Also, on an aside, a quick google search for ''ogskywakler' produces a Battlefield 4 player statistics of K/D of 0.68 - so maybe he should stay quiet!!!
