Troubles...
The problem with letting everyone post ip's to be banned is quite obvious. For example, I watched all three demos which dt posted. I wasn't using a wallhack, but I didn't see anything happen which couldn't be explained normally. Maybe if I had used a wallhack to view them I'd see it differently. What I did see was all of EXT being quite pathetic and rude with all their comments. Again, I'm not saying there wasn't any wallhacking going on but it wasn't as obvious to me as their comments would lead you to believe.
As far as them not spraying all the time:
Why spray all the time, with the new gun temp setting alot of us have learned not to spray so much. Since you must have had gun_temp off EXT was spraying alot, especially while rushing into the base. Also remember, this map was indune, one entry into the base. While watching the demo from the "hacking" teams view I could see your spray and hear your guns, this allows the "defending hacker" to know almost exactly what your position is. By them not spraying they don't give away their position until you see the impact grenade flying at you.
Looking through walls:
Could be, probably should be watched with a wallhack to see if the "hackers" are following targets or such, but it wasn't obvious to me. Recon sometimes seems like a wallhack... could be just recon.
Running back into his base, running from your grenade? It looked like to me he was simply going back for another grenade.
My point is that there needs to be solid prove, no guessing. Pinobot and BSoD have proved that prove themselves and should be perm banned. Others deserve the same perm ban I'm sure. I think alot of people have wallhacks or cheats, but I don't think very many people either know how or choose to use them.
I would like to see the wall of shame list regulated somehow and will volunteer some time to help if needed.
