It really hit and miss. In my case while there are several hits, most of the movies are very very aged. However they do have a wide range of younger content. I know you can watch enough Hannah Montana to want to hang yourself...
I bought the family a Roku box a while back now and it's got the heaviest use from the younger ones.
Also a side note: I hope MS makes netflix FREE. I can pay monthly to get their gold package (which is only needed for those who play nothing but CoD and Halo for hours on end) in order to use netflix. Why spend the money when I can spend $100 and get a Roku box without having to worry about fees?
You clearly have no idea how Steam's banning system (VAC) works. There is no way to "report" someone. Not only is VAC automatic (it catches specific software that makes adjustments to the game as it's being play), it's also generally out-of-date. The only way you will be banned is if you use old hacks on a secure server. There are also many unsecure servers that can be played on. Also, VAC tends to be slow on updating which hacks it watches for.
Steam doesn't review bans for a simple reason: Hacks Lie. Also, the average person caught cheating is a whinny 12-year-old brat. Very rarely are people banned incorrectly. The only thing I can think of was an old HL1 client-side mod which let people see "bloom." It was later found that VAC would catch this as a hack. Once this was found, the developers of the mod CLEARLY noted that it was caught by VAC and should not be used during online play.
Always draw your curves, then plot your reading.
