I'm going to take your request seriously, so bear with me. Grusch isn't the only whistleblower that recently came forward. He's just one going through the proper channels.
About two weeks ago, someone with incredible detail claiming to be a molecular biologist wrote the most detailed breakdown of alien biology I've ever read on Reddit. I archived the original on kbin here, as there was a lot of odd mod activity around the post (comments deleted, author disappears, etc).
I suggest you take a look. If it's a LARP, it's the best I've ever read.
