Have you ever thought that maybe most of the IMG (and even CR) suck at PvP and they don't want PvP and shooting them means ruinging their fun? And since they have the means to avoid that, your fun will be ruined. It's you or them. I've seen cases when CR offered fair fights to a single guy and because they did that, they lost 5 ships one after the other instead of sending all of them at once and take him out. Yes? Mercs and freelancers need the blue message to make money. Well, change your operating area or find another way to make money if this is not working.
I, for one, hate this thing the most - offering blue messages to mercs. I hate this more than being pirated for 20 mils or stuff like that. But this is just me.
To be a merc should be hard and IMG are doing their job keeping it that way.
