YLC been blocking you again? Maybe you really are Mafia this time???

Otherwise, I can't see a roleblocker blocking someone for three night phases...nobody has been really scumming... Other then maybe Beskar (but you always are...)

Only people I could think of having the Brass ones to pull this off would be...

Reenk
ATPG
TinCow (I admit I have never seen him as Mafia yet...)
Beskar (he is always suspicious)
