Seems that Muderous wants to fuck around..
He put in on his page at
http://www.spherecom-software.com/cg...i?id=murderous and get every visitor to be counted as clicked (maybe he took it off all ready).
A good robot can (of course) act like a good robot... and make the system think it is a clicked URL.
Simply, We count unique IP in the last 30 minutes in order to eliminate double clicks or refresh of topics on the board. In the same time it eliminate stupid robots.
