Is that the reason you combat logged three times? By posting it here you're shaming no one but yourself and FDev.
You're shaming yourself because you don't know how this game works, and performed a move marked as cheating by FDev, for multiple times. Then you came back, and accuse other players for cheating, because their engineered ships had better performance and lag, yes, we know that but only you don't than your stock 'conda?
You're shaming FDev by cheating without being punished, and showing us how the network mechanics is a pile of mess. Said ganker had your ship blown up in his client, then you magically log in again with your ship in one piece. Disconnection from other players happens. Happens once I blame lag, twice I blame hard luck, and there's a third time.
I'm not said ganker, in case someone thinks that way. I just heard some stories, and I trust said ganker more than a stranger who has suspectedly combat logged. I would apology in the case you did not combat log/task-kill, but that means all the blame goes to FDev for not developing a proper network environment for player to player interactions.
