Online POS
We were fighting some guys in a C4 WH for a week and noticed that alliance members were also using the POS. So we applied an alt to one of their industrial corporations in order to get access to the ff for ourselves. I don't know why you would allow someone in your alliance without an api check, ts interview or kb check and give them the right to shut down your POS (in another coporation in said alliance). In total we got about 50 billion, the contents of 2 more ship arrays + 3 corp hangars + 2 chimeras are unfortunately not on the screenshots.
Offline POS
We started bumping ships out first before we realized that they actually really gave alliance members the right to shut down the forcefield, unfortunately we couldn't take the fuel out though.
Some of the t1 ships we later found in an additional ship maintenance array, we actually started shooting every t1 cruiser hull, as we couldn't move it all.
After we got all the ships they also sent out an alliance mail

We also later got a hilarious T3 kill as one of their members accepted a fleet invite from my cloaky alt and warped to my main waiting a in a bubble

Cleaned up POS
Unfortunately they onlined the POS again but it looks a lot nicer now.
