First, choose a player (me for example ;_; ). You can pick up your victim from the ones in Cock Fights (or wherever you can find one) ; click on their user name, and their profile page will appear. Click on one of their massage parlours, take a girl on a ride, then you'll be able either to kidnap one of the girls's player, either raid & plunder the sh*t out of their massage parlours.
Click on "raid" after you took a girl on a ride, then select your allies (= security staff), make sure you have enough energy, and click on "raid this place".
The world needs trouble-makers. If not, Batman wouldn't exist... and neither would DICK Robin. ;D
