OGHF hacker, (OGHF) hacker, [OGHF] hacker, {OGHF} hacker
Some unscrupulous server owners are using a script to change the name of players to these names.
It is relatively easy to do unfortunately:-
self setClientDvar( "name", "[OGHF] hacker" );
So some players will come onto your servers and not realise that their name has been changed as it will only change as they leave the said server and join another.
It is obvious that whoever is doing this is upset at OGHF... poor baby
Just something to be aware of
p.s. if it happens to you try to remember the last server you visited to clock who is doing this
