Assets blocked in a station

There are a number of options I think.

1: Firesale everything in the station from space (assuming it is a normal station with a market place and not a citadel that doesnt have a market)
2: Do you have a clone in that station? if so jump to it, do not undock and try the sell the stuff off that way.
3: Ask CCP to move it, they may not do so but if you are returning they may move it all out to high sec.
4. see if you can join that corp, or another corp they are blue to (they will have docking rights i assume) and stay there or move the stuff out.

That is all I can think of currently.
