Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
trackers/hooks aren't detectable with antivirus applications. Hooks are internet connectors, they connect to a website when this application is running, creating security holes so your computer is more vulnerable to attacks and hackers will know your browsing information and windows weaknesses. Hooks may also download unwanted software that is encrypted on your hard drive. An anti virus scanner canot pick these up because an internet connection is not spyware, otherwise your antivirus product will tell you to disconnect your internet and never use it again.
Searching through the internet, I found indeed this program had hooks.
