Why not just create a new starting system that acts as a gateway. Low levels could start there and there would be noob friendly missions/mining zones for them to make money, then once they hit 30 they can head into the real world, or maybe leave whenever you like,f or people setting up chars.
In the system you'd have a jumpgate to each of the main houses, along with a few pirate faction bases. (Maybe even have NPCs in this starter system to help them get their rep set up properly before hitting the gate)
This system would be a one way system, meaning once you leave you can never get back in.
Only problem I can see is all the low levels and new players being stuck with the hackers and cheaters... but its like that anyways at Manhattan.
EDIT- Never mind it helps to read the thread sometimes before blindly commenting...
Iâll carry this flag
To the grave if I must
Because itâs flag that I love
And a flag that I trust
