#120000s - Game Hook -> Can be a lot, the name of this kick is based on the way the cheat works, its mostly a dll hooked into quake (can be multihack, af etc.) .

ofc PB won't tell you which cheat a person used, but the way the cheat works.
a gamehook allows you to have a cheat code hooked in the q3 executable. A very simple example would be allowing all cheat protected cvars, like r_shownormals 1

edit: about the link you found, it may be the said demotool, however it seems to be multirecord which might allow you to have extra infos from other players.

it is an external program, it doesnt matter if it is ment as cheat, but if it works like a cheat. - which it does

edit: also 1 kickcode can have more then 1 program behind it.
