Crossfire Hack to Nullify a Hack

If this is not the correct location for this post please let me know as I am new to this forum. That being said,
Is there a way to code a hack so that if there is another player using any hacks they would not be able to damage you, see you through walls, etc.
The damage part is what mostly interests me. I know there's many who play with hacks but I myself do not. Not that I think its wrong, it's just more fun to not use them. My issue is getting into a game and someone joins eventually after I was doing so well, and starts knifing everyone while out of the map or one hit killing everyone while their team won't kick them, even when its obvious. So to avoid that frustration, is it possible to create a hack so that anyone using hacks cannot do anything to you. Even if it results in you not being able to do anything to them, that's still fine. I'm thinking a way so that if anyone is using any scripts or codes that you specify are "not allowed" so to speak, then they can't damage you. If it is possible, how can I go about doing that.
Questions are:
1: Is it possible
2: What sort or coding would I need to do it
There's coding for all kinds of stuff, but I don't see any on player damage (for you). There's some out there for damaging other players but not for reducing it on you. (I wouldn't want reduced damage from everyone. Just no damage from someone using any hacks).

so what about if ur enemy use no recoil .. what can u do with that...
NO WAY :|

What do you mean? Are you asking what can I do, as in modify their recoil? That's not what I mean if you're asking that. What I mean is that anyone using a different code than what I say, for example.
Perhaps listing what the "default" is for the original files. And if anyone has them set differently (aside from killmarks and sound files of course) then their account basically can't register that my account is there to do damage to. I'm domy best to explain it better. I'm thinking of a hack to basically say "These are the correct files. Opposing player's files are ______. Damage reduced to 0". My thought is, if you can increase your damage, then why can't you decrease your damage taken? Or, just increase your armor to nullify the opposing player's bullets, and have it so it only "activates" when the bullet/knife actually impacts your character. Hopefully that clears it up a bit.

There's no way to make yourself "invisible" to the server only for the moments your attacked by player using the hacks. Maybe something to tell the server your actually at your spawn point but not have you appear at the spawn. Your body would stay there while being attacked and lets say, if someone shot into an open area in the spawn you could die because your hitbox is there. Even if it results in other players not damaging you for those few moments, it wouldn't be too bad compared to someone wiping out everyone non stop. Obviously if the opposing team isn't kicking them, I won't mind them dealing with a little "invincibility" for half a second.

Another way might be to have it so when the person using a hack targets me, my hitbox moves to the spawn point. So for example: if they shot me while they had the hit boxes viewable, they'd see my hit box in the spawn as they looked at me. Just an idea.
Is there is specific reason for no hacks actually having something like that but able to have higher damage capabilities? I guess that should be the first question.

That actually sounds exactly like what I'm asking. Any specific reason why it would be hard?

First off, your hack would need some way of communicating, aka Client serer communication, so basically say you run the server, when a player logs on to your hack, using the client, have that client log the username they use, and send it to server, and log that to a text file, now inside your hack loop, read the player data logged to the text file into an array, and read the player names in your lobby to an array and constantly compare them, if a player name in your lobby matches a player name using your hack(aka the logged text file), have the server(you), send a pre proggrammed command to your client, that when the client receives this, the client nullifys itself, aka you can close the client socket, this will kick the user from using your hack, or you can just set all the hacks on that client off. (its not exactly what you want, but it works)

I just came up with this idea right now i didn't test it or even tried to make it so Good Luck
