i believe that it is actually pretty difficult to have most of your shots hitting chest/head with a scout. looking at the psychostats for players at scoutzknivez server the majority of hits go to the arms. maybe i'm wrong..or source is completely different. i mean..just look at how you do with a scout Mr_Me [8D]according to the stats of that particular player, he does have the most kills with the scout, maybe suggesting he uses that very often.
i agree that stats don't tell the complete story, but it is still possible it may be hacks. i suggest you record demos before you ban.
maybe iamcompletely wrongabout this
