I don't know if I'm on the right track, but here it is:
These members were posting when the flow against Janna started:
adRHCP
(Janna was in big danger, but he voted Soren and didn't try to save her), Gep
(Janna was in danger but didn't save her. Voted Klin), Klin, Sabet
(changed votes all the time, but didn't try to save Janna), X, Jasper
(didn't try to save Janna), Zach
(tried to save himself, which is normal), Melo
(voted Janna), Soren
(didn't try to save Janna), Fresh
(voted for Zach), ILiveforJuve
(didn't try to save Janna), Tomice
(didn't try to save Janna), Fred
(didn't try to save Janna), Kyle, Sheik
(didn't try to save Janna), Voller
(was online, but didn't react and didn't try to save Janna). I was jailed. Janna was also there.
That's 18 members.The 9 who weren't there are:
Ze (lawyer)
Lemon (detective)
Piotrr (civilian)
----
ALC
Salvo
Mr Chocolate
Matt
Cuti
Osman
------------
These 6 at the end. They weren't online and they couldn't save Janna, even if they wanted to.
Neither of them voted for Janna before that.
For example:
ALC voted Zach
Salvo voted Zach
Mr Chocolate voted Soren
Matt didn't vote
Cuti voted Soren
Osman voted X
----------------------
When was their last vote?
ALC's last vote was at 12:33, just when the voting started. He casted a vote for Zach, and didn't come back. That was his only post that day.
Salvo's last post was at 14:42. Voted for Zach and went to sleep.
Matt's last post was at 19:35. But he didn't vote at all that day. He knew that Janna is in danger, but didn't vote and didn't try to save her.
Mr Chocolate's last post was at 13:10. Janna still wasn't in danger. He just voted Soren and he disappeared.
Cuti's last post was at 18:10. The result was 6:4 for Zach, but he didn't give another vote for Zach and sticked with his vote for Soren.
Osman's last post was at 19:10. The result was 6:3 for Zach. Janna wasn't in big danger. Osman kept his voice for X
---------------------
Can we take anything from this?

Fresh, ALC, Salvo, Mr Chocolate, Osman and....?
