Well done finding those.
Looking at the links and the clues - id looked at the 'spot a rogue casino' page but never noticed the Halloween image
I also did a lot of searching relating to Kodiak - but ended up looking at google maps and trying to search the site for Kodiak but with little result.
Didn't have a clue what the no banned users allowed was (tried looking for banned users to see if the attached image related to one of them, but gave up), and you already got me - i was looking through the previous days hunt pages thinking it might be in there, but gave up again when i couldn't find it.
