Indeed, my pledge money well spent even when I got screwed with offline mode. And it doesn't look like they are getting any quieter. Presumably being griefers they just can't comprehend that it can't be fixed without a major rewrite. Keep up the good work, Frontier!
I do feel bad for the bounty hunters, as they are probably the most impacted by this. Id be willing to bet that the pirates and pks are the most likely to abuse the alt-f4 escape knowing that bullies are cowards at heart, but as you say the way the p2p architecture works and the low priority the devs put on pvp interactions I just don't see them going through the rewrite it would take to address it anytime soon.
