It should be noted, however, that if the enemy does a Fleet scan and sees that your fleet is a fake attack, they can then fleetcatch you straight back and you loose your fleet. Ditto for any co-attackers. Also, it still applies to just a normal (non-fake) attack too, however it might take two or three ticks worth of launching to actually catch you (as you might recall before the tick, or land anyway (<3 Benneh
), and thus need to be caught).
If you intend to do nasty things like that to people, get someone to constantly JGP yourself (or JGP a returning fleet) to see whether the hostiles start piling up.
