mysta (wallhack?)

So, after our recruitment thread http://www.crossfire.nu/?x=forum&mode=item&id=19958 one of the most promising tryouts, although with no significant clanhistory, was mysta. However, upon closer inspection of his demos, something didn't feel quite right, and so here we are in the cheaters forum.

His demos from yesterday are here:

Watch them and you will find lots of suspicious moments, plus some that, in our opinion, are more than suspicious.

In particular some that I noted down (not necessairily the most obvious, I didn't watch all of the demos) are:

In the 2nd demo, 213802-supply, fast forward around 5:50 and you'll see mysta killing a hidden opponent in the tunnel with an action that can only be explained by a wallack.

In the 7th demo, 225130-sw-gold, watch around time 10:50, you will see mysta starting to build the barrier, and then stopping to stare at an opponent proned in the middle of the courtyard. He sees him, but hes not sure whether he's supposed to be seeing him or not, so he doesn't shoot.

A similar situation occurs in the same demo around time 8:20; in particular when the head of the opponent is perfectly visible above the stairs in front of the bank, but mysta doesn't shoot because he's not sure if it would be visible without a wallhack (or at least that's my interpretation).

And of course, also suspicious is the consistency of his general awareness of the positions of the opponents

If someone wants to help me by making some avis of these moments or any other wallhackish scene, I'll be grateful. =)
