Why should they message you? When it comes to putting down a player there really isn't any need for small talk. Anyone with half a brain in their head will be feverishly using that time to escape.
The way I look at it is that you got a very cheap lesson on what to watch out for around other players in Open. When I'm playing around strangers I assume they will try to kill me without "provocation" and act accordingly. If I'm playing around my friends I absolutely
know they'll try to kill me and act accordingly
The bottom line is that it didn't effect your financial outlook and now you know something you didn't know before, making you that much more secure from a gank in the future.
