i'm frankly rather surprised that they're not restricted already
Nobody has posted something like this.
There was a similar restriction made one day that was the result of a single server, someone had made the server name kompressor's server, hosted a server with his shapename as kompressor, and his ID being set to 1 and EVERYONE was fooled.
Shortly after, Badspot posted on the gallery topic, extremely pissed off and then changes were made, server names required the actual name, along with shapenames officially being unchangeable, breaking some really cool bot mods possibilities, and ID's in the player GUI being unchangeable.
