Blocket IP Adresser

Din IP adress vil blivee blocket hvis du prøver og logge ind mere end 10 gange, uden det korrekte password. Du vil kun blive blocket i 1 minut, og så vil din IP adresse blive slettet fra listen.

Brug sidens kontakt link til at e-maile os, og vi vil fjerne dig fra listen kun vis det er påkrævet; men for det meste bliver det ikke nødvendigt.

Vi vil lave et link til en hosts.deny fil, så medlemmer kan kigge på 'gerningsmanden' og uheldige medlemmer der skriver med deres tæer.
