Firstly, the demo is a little short and inconclusive. I don't think it shows an aimbot, however. If it is an aimbot it is very smooth and unnoticeable. There was no pressure on the kills so I think any decent player could have headshot all four of them.
So my verdict (based on the demo) is that he's clean.
Secondly, the steam account and steam ID both match - So it is not the result of steam ID spoofing by another player/hacker. The owner of the account is Greek, and the IP address of H0MBRe was Greek. I took the time to spectate him playing on a Greek server and he was speaking in Greek and responding to questions in Greek. People were calling him H0MBRe, despite having the alias ohgodfleas. This doesn't seem like the behavior of rizla or any of the other fakers who plague Ambrosia. I watched him play for about 10 minutes before being kicked. He seems like a very skillful player with quick reactions, but I can't confirm or deny that he is or is not using cheats.
That being said it makes no difference to the verdict as punishment (if it was ever needed) as this is based on the evidence and there isn't (in my opinion) any evidence of hacking.
Sometimes, rarely, you come across a player who is considerably better than you and you have to swallow your pride and accept that. Not everybody is a cheat.
However.. There were some things that seemed confusing and out of place. One being the fact that he's played 840 hours of CS, CS:S, CS:GO, and QuakeLive in 2 weeks - Which is mathematically impossible as there's only 336 hours in 2 weeks. So how he's managed to get 504 more hours than are present in 2 weeks is somewhat amazing in itself. The second fact is that he only has 4 friends on his friends list. For an account that is 8 years old and as active as it is (albeit impossibly) I would expect someone to have more friends. But, again, that is still not evidence that he cheats.
