There is a trick to make people believe they are being warp scrambled by you.
Get close to the target ship dump some stuff from your cargo into space. Rename the container to "You". Target the the ship and target your container (the container must me the selected target). Start your warp scrambler.
The guy in the other ship (and all ships around) now receive the following message: "Jimbo is trying to warp scramble 'You'". A lot of people starts shooting you at this time get will get concorded for this
