I think I understand why some people said they were disappointed in their role. In a themed game one would expect to get a cool ability, no? So this turn some users got roles that are just townies with Mortal Kombat names, thus disappointment!
About Mario, I agree that he has to get posting, but according to his profile he hasn't been online for the last 3 days. I see it a a little pointless to try to pressure someone to post when they're not even here.
For the other possible lurkers. I'm looking at noname's chart for posts and if they haven't posted recently (or at least what I can remember 
)
Falcon ZERO - not online for 19 hours
trangentspree ZERO - 3 hours ago (hasn't posted at all on day two, but quite a bit on day one)
GodOfWar_3ever TWO - one hour ago
Silver-Tiger ONE - 5 hours ago (an FoS with nothing much else)
SnakeEyez ZERO - 5 hours ago
Who I would be suspicious of more are the people who have been online recently.
EDIT- ah, yes, I also discounted people who have excuses.
