[COD4] Banning/Removing perks by changing offsets?

[CaptainSlow]

I'm trying to ban/remove the Last Stand and Martydom perk from our COD4 servers.
This can be accomplished using B3 bot or Manu Admin Mod which will kick the player after the first kill has been made with the offending perk, due to COD logging limitations.
However, after some googling, I found this topic in which someone claims it should also be possible to remove the perk from the player's loadout/class upon connecting:
[---- LINK REMOVED----]

Has any of you heard of this before and more importantly, can it really be done?

Thanks!
