This is not related to robots but since someone took one of my domain's years ago everyone needs to spread the news. Shareaza the open source P2P program has lost its domain name to some pay service. Shareaza has moved to this URL.
The new owners of the domain are pushing some pay software labeled shareazav4.exe this is not the real shareaza which is at this time v126.96.36.199
