You can never tell with a ninja penguin, he might never have actually left! Ninjas are masters of obfuscation, deception and concealment. Perhaps we should ask him where Raxxla and TDW are?
He posted yesterday (https://forums.frontier.co.uk/threads/stations-labelled-with-fsp.140306/post-9117228) on the “Stations labelled with FSP#” thread.
The idea was that if Fed spaceports are consecutively numbered, then a database of all 10,500 currently reported by EDDB would reveal any missing stations and hence might lead to TDW’s stealthed station (since it is likely to be a disused fed station).
However it has been pointed out that:

However it has been pointed out that:
- the FSP# uses only 4 decimal digits, therefore there would be repeated numbers
- moreover they are not consecutively numbered but the FSP is generated by a procedural algorithm that depends on station name and the star system (presumably name, though might be galactic coordinates).
- The Federation has lost systems, and therefore station FSP likely have been lost.
