I mean it is really your own thing what you are reading out from this post on that Forum. My personal view at the moment is that it is a 90 per cent or more chance to be fake as long as we get no reliable source. Everybody can post something on the Internet. I mean it would be a good thing and clearly would make clear that life span is longer but the first chance we could get more information about a potential Expansion (and also potential more DLCs) will be mid September when we get the full annual report.
By my judgement:
1) Clever enough to use/steal a real junior employee name at the zoo. To clarify, it would be nice if we could contact this person. Then if it wasn't them they could clear this up really quickly.
2) Clever to use convincing halting/not that fluent english.
3) Clever to edit the post less than 1 hour after the furore. So far they haven't logged back on yet either so maybe tomorrow when they realise how much they've screwed up they will delete their account and their post. It would be clever if the troll did this because it mimics real life behaviour.
4) Clever enough to resist leaking "lots of stuff" for attention. Impressive self-control for a troll.
5) Clever enough to pretend to not know much about the game ("first expansion pack")
6) Clever to link the Frontier partnership with the broader theme of detailing a bunch of other promotional efforts made by the zoo. If these promotional efforts exist, this troll really did their homework.
Basically, if this is a troll they are playing 4D chess with us. Of course, such people exist. But equally, I think it's possible this is genuine/inadvertent screw up by someone.
