last sunday i was listening to my local radio station preacher talking and my kids playing in living room listening to me play online, i shot down a player he tuned to me swearing his dumbarse off, my 5yr old daughter asks me daddy who was that? what he say? why? my boys-whoa dad! he said a bad word. geez i think hi-tech has to auto block cuss words, dam that was hardcore-i logged off immediately. next time i log on i will make sure i have my headset on. and for the puke who accused me of hitting my kids, i hope i don't run into you while i am hunting alaskan bears or whales 
I agree that is a poor display of behaviour, and just about as classless as could be. My larger question is this... You hunt Whales??
I think that stokes hit it right on the head. An approval option for voice tune would be a great addition. I would even support this addition for private text. Sometimes after I have shot someone down, I really don't care what the have to say to me.
I know what you mean there, but a lot of times after a good fight where I get shot down, I like to discuss the fight or a move they might have made that was good or how I could have done better or whatever. I agree that it's easily abused, but it can also be a really good learning tool, and a good way to have a nice conversation with someone you havne't really met before.
