I'm not too familiar with CS:GO. Long time player of CS 1.6 and I can spot a hacker easily there. CS:GO is quite a bit different, but I spotted some gameplay that was fishy as hell.
Here is the information from 'status':

You can see his account is very new... 5.9 hours on CS:GO and he won quite a few rounds on gungame. I know that isn't reason enough, so I recored a demo and attached it.
(I hope it is attached anyway... I can not view it)
Can't examine the demo for right now, haven't downloaded GO on this computer yet. However I checked out his stats, they seem extremely average so not sure about the possibility until the demo is reviewed.
