How about if local GalNet and/or station announcers in High Sec systems gave warnings about, say, "increased pirate activity in [neighboring Low Sec system]. Pilots are advised to avoid"?
Then the information is available and flagged for new Cmdrs without being totally 'in your face'.

That would cover it provided they made it REAL and not just a matter of "stroll in there harmless and get a few harmless NPCs to practice on" but "wander in competent or better and get swarmed with engineered elites" - scaling spawns to player rank really did throw a huge wrench in making the system security levels and states mean anything. All that they change now is the rate, not what you're likely to get. If nothing else it needs to have the relative weight of the two factors substantially readjusted.
