fysiks, steamids are the only unique identifiers for players, but they can be changed. So, they're as reliable as ip addresses or names when you're reading them with a third-party addon like AMXX or SteamBans. It's just a bad idea to build a system on top of steamids that are known to be changeable. It was always a bad idea, right from the start, but perhaps the developers of SteamBans didn't realize this during development. Perhaps they were hoping that no one would figure it out, which is a Really Bad Idea.


What does SteamBans do?

SteamBans uses a secret hashing function to convert a steamid to some scrambled data, and then deciphers that scrambled (or hashed) data on the other end. So, if you use a steamid changer, then SteamBans will hash the fake steamid.

Now, if SteamBans could grab the real steamid regardless of whether or not it had been changed, then the problem would be averted. For example, VAC grabs the real steamid.
