Not wanting to affirm a known scammer, but I just sold this corpse to them for 1.2B as you can see in my thread below.
This is a legit corpse, though if you want to buy it, you should use a trusted third party like Elizabeth Norn and NOT use trade windows which is a trademark scam of Serenity Fireslayer.
However, I can confirm I was in Otoh on this day during GM week and I witnessed both the destruction of the Cerberus and capsule and I scooped the corpse on that day.
For interest, Bjornbee was FC for the Gamesmasters on that day.
