Menu-logging doesn't have a lot to do with that, though.why do you think nobody can stop griefers legitimately?
Garry Griefer is blowing up Sidewinders in Eravate in their Fer-de-lance when they're intercepted by an Adrian's Alpacas patrol.
Scenario 1:
- Garry Griefer exits to menu after 15 seconds. While the Alpacas are skilled and heavily armed, the FDL is too tough to be destroyed in that short a time even when it is flying straight and level. They content themselves with dropping the shields and dealing a fair bit of hull and subsystem damage.
- Garry logs back in to solo to avoid being seen, flies to the nearest station and repairs.
- Garry logs out again, logs back in to open and returns to supercruise
Scenario 2:
- Garry Griefer high wakes out, using SCBs and evasive flying to be gone in 25 seconds (10 cooldown, 15 jump). They take minor damage if any.
- Garry jumps back to Eravate
Scenario 3:
- Garry Griefer attempts to fight but is rapidly destroyed because they're not used to fighting ships which have weapons. They pay the rebuy from their billions of Robigo funds, respawn at Eravate station fully repaired and loaded, and return to interdicting Sidewinders.
The menu-log scenario is the one which stops them interdicting Sidewinders for the longest time, I think. (Even cheating, by killing ED, then restarting it, is probably still slower than the other two scenarios, since it'll take a good 30 seconds to get back in to the game after that, plus they still have to do the "sneak away in solo" trick)
Maybe if Frontier were to cap earnings at 2M/hour from the "optimal" solution, introduce a steep wealth tax on players with over a billion credits, and reset everyone back to Sidewinders to level the field, it would be possible to stop (as opposed to mildly inconvenience) aggressors by blowing them up. Since Frontier won't do that - for obvious reasons! - the purpose of patrols has to be to keep the aggressors away from their targets, not necessarily to destroy them (which is why interdictorwinders make very useful tools for this)
