I see a game mechanics problem with this. There is no possible counter to it.
Scenario: pilot logs on immediately after downtime and immediately jumps to the ineighboring target system. Warps to a safe spot and coaks, then AFKs all day.
It is impossible to scan him down.The only way to find him it so accidentally gets within 2500km; statistically highly unlikely. I have a safe spot that is about 900,000km “north” of the sun. No one s going to bump into me by accident.
It si just griefing, especially in a system with a cyno jammer so he can’t hot-drop a blob.
A couple suggestions: the cloaking module has to re-align itself every X hours. Turns off and has to be manually re-activated. Or it uses fuel, like liquid ozone, more than the typical frigate’s hold can carry for 23 hours fo constant running.
Again, it si just griefing and there is NO counter to it making it manifestly unfair.`
