Yeah, booting someone who hasn't taken his turn in 3 and a half days is certainly a capital crime.
this is not the problem (although its annoying), but before you booted him he had said this: "guys, ill be out for some days. this turn will take some time, because i have to see the situation of everybody, dont kick
and this: "By the end of the day ill take my turn".
you saw he was active in those 3 and a half days.
