Well i think all agree that its stupid that the blackmailed person can just vote each person once and then everyone knows he/she is blackmailed. There definitely should be an option for the Blackmailer to disable voting for trial during the day (but maybe not voting inno/guilty). What now happens is that when a Sheriff gets blackmailed he simply votes each person once and then spam a few times the guilty person and in my opinion and many others is that's not how blackmailing suppose to work.
