Combat logging isn't a problem, as far as I can see; Surely most PVP killing is a *wanted* PVP player with murders to their name attempting to murder a *clean* PVE'er. If the PVE'er combat logs, the PVP player has won. They weren't going to get any rep or any bounty for it anyway, so the only difference is that their own bounty hasn't been increased from assault to murder. I honestly don't understand the anguish CL'ing causes these people and I don't understand what they even get from it in the first place.
If FD were stringent about enforcing penalties for combat loggers, the whole game would suffer massively because it would force less diversity. Rather than min/maxing your trader for cargo, explorer for jumprange, and miner for gathering efficiency, we'd all have to play the PVP meta game in open. CL'ing is an escape route for people who didn't want to lose everything just because they chose to leave the hangar in a PVE ship instead of a PVP ship. I'll definitely log in my unarmed explorerconda after coming back from a 6000LY passenger mission. The PVP'er gets nothing from the kill anyway, but if I'd gone out with a massive shield, countermeasures, module reinforcements and weapons, that 12000LY round trip in a heavier PVP-meta ship would have taken an extra two or three hours of jump/scoop/repeat gameplay
There's more to this game than murdering other CMDRs and I think if you're madcrazy upset that you didn't get your pretty explosion then you have some serious psychological problems that you should look at first; It's not healthy to get your kicks from causing misery to others, especially when it's often "bully vs defenseless" in a lot of Elite's PVP encounters. If you watch the "complaint" videos where the attacker uploads footage of the combat logger, you'll often see the attacker send the message along the lines of "cooperate, submit to scans and hand over cargo" or similar but then they start shooting before even giving the victim a chance to even reply. Most of them are simply out to send traders/miners/explorers to the rebuy screen for no obvious reason and by demanding that traders/miners/explorers don't combat log they are basically asking FD to make sure everyone is playing a PVP game. Sorry ladies and gents, but elite is primarily a PVE experience. There's no way I'm going to agree to anything that detracts from that just to appease the 30% of players who PVP 10% of the time.
