I have now been purged 3 times whilst offline. The latest one is now the end of it for me. My Black Ice base was attacked by the Black Legion whilst I was offline. They destroyed every single station, the entire building in which I had all my belongings and killed everyone except T1 thralls. All of my T4 crafting thralls are gone, and since they no longer drop are now unable to be replaced.
Screw you Funcom, Games are meant to be enjoyable. This was a solid base with over 20 T3 fighter and archer thralls and it looks like nobody defended anything. Every storage container, every station, even the alters are all gone. I see no point rebuilding when it seems the same thing will just happen again.
edit: Changing title to be less inflammatory
