I agree but combat logging needs to be dealt in conjunction with crime & punishment as a joint effort one without the other unbalances the game.
These two problems are so easy to fix:-
1) Make the Combat Log timeout 120 seconds. Your ship remains vulnerable for the whole time

. If it's destroyed while you're logged out you get to see the rebuy screen when you log in again.
2) There are no real punishments for Griefing. The punishments should be hard enough and last long enough to dissuade CMDRs from Griefing other "unwanted" CMDRs ("Wanted" CMDRs are fair game for anyone). First some definitions:-
Piracy: Find a ship with cargo, stop the ship, collect dropped cargo, fly away
leaving your victim alive and able to reach a repair base (that bit's important).
Griefing: Destroying a CMDRs ship, by whatever means (including suicide-by-ramming) for the hell of it.
Piracy is fine. I have nothing against piracy. Next time I wipe my save I'll probably try it myself. It's certainly on my ToDo list.
Punishments for Griefing would include:-
1) Expulsion from the Pilots Federation - making it's ship-rebuy insurance policies unavailable to you. You would not be allowed to rejoin the Pilots Federation for an amount of time that increases exponentially each time you Grief a CMDR.
2) You remain "Wanted" for the entire time of your expulsion, regardless of the number of times your ship is destroyed,
even if you wipe your save!
3) The star system you are in and your bounty would be broadcast in the 20 closest systems to any you are in.
4) A bounty will be paid upon the destruction of your ship. It shall be N times whatever you cost the CMDR(s) whose ships you destroyed. The bounty shall include the value of the ships, cargo, bounty claims, exploration data, etc that your victims lost. The bounty lasts the entire time of your expulsion. The bounties paid out would be paid by
you - initially they'd be taken from your funds, then any goods you have will be sold and finally any ships you own will be sold. Once all of your assets have gone, the Pilots Federation will pick up the tab (enjoy the E-rated freewinder).
5) No CMDR can claim the bounty on you more than once a day - though they can attack you when they like.
6) The Bounty against you would
not be claimable by CMDRs who've been expelled from the Pilots Federation at any time in the previous N months.
The multiplier N
This would start at one, but would double with every crime.
N would decrease by 1 every 7 days of real time elapsed until it is down to one again.
