Read this clearly, what you just posted was a way which enables people from interrupting the data sent from the server to client - and altering it, which is nothing but cheating. These sorts of tool are against the Terms of Service of Valve coorporation and hence illegal.
Since this is the first time you have posted this, a warning will not be issued. Please read our AUP and make sure that you do not repeat such an offense. For posting tools which threaten the security of Half-Life and it's modifications (which affects ESF directly as well), I can personally make sure that you are banned from our entire esforces.com website. Please heed this warning positively.
