Most multiplayer games benefit from excluding large (if anecdotal evidence is to be believed) groups of players. It's a little-known way of turning a healthy profit.
On a (slightly) more serious point: ED has a problem with its 'crime & punishment' system as a whole, not just conceptually but also on a practical level, and that approach is manifesting itself in behaviours such as 'combat logging'. It seems that the game was developed with an 'anything goes' mindset which is being tested, to breaking point, with the advent of various issues, with combat logging being but one.
Presently the risk rests almost entirely on the shoulders of the Seal (aka. the 'victim'). There are no material consequences for behaving like a Seal Clubber. Why is it then so surprising that some Seals, when faced with such conditions, chose an ungraceful exit from that no-win situation? One might argue that it was the Seal's fault for allowing themselves to get into that situation, which is a point with some merit; or at least it would be if ED had a sensible and practical, and most importantly, transparent, Crime & Punishment system because then the hapless Seal would be equipped with the knowledge of where, when, and how to venture into certain territories. Right now it's a crapshoot, regardless of where you are.
Combat logging should remain an undesirable action, granted. (Accepting that with a P2P solution you can't reliably diagnose ungraceful disconnections, or do a whole lot about it in terms of retaining some sort of termporary presence in-game.) But FD need to understand
why people do it, carefully, and address the areas of their game that are so weak that it forces decent players to do the indecent thing. (Accepting that some players will always be penii no matter what.)
There is at least some evidence that FD are thinking about such things but it seems to have gone no further than canvassing general opinion on the notion of some sort of geared Seal Clubbing consequences. It's a start but I get the impression that some sort of cockeyed ban hammer is already in the forge, being crafted to hammer flat behaviours that FD don't yet seem to want to accept are being driven by a lopsided Crime & Punishment system.
Punishing combat loggers but doing nothing about why people do it is perhaps the most short-sighted and potentially damaging solution in the history of potentially damaging solutions - relatively speaking.
