@ Peterlund: Good questions. I hope these answers satisfy:
1. Developer Questions:
Motivator: Yes, the target is informed that they get an additional night action (otherwise they would not be able to use it) and yes, this effect lasts only one night.
Vanilla-iser: No, the effect is permanent.
Voteless: Yes, it is the Developer that becomes voteless, for the next Day phase. Their vote is counted and appears in vote counts during the Day's progress, however at the EoD, their vote has a weight of 0. The GM will NOT disclose which vote was weigthed at 0 to the other players however it may be possible to deduce which wagon the voteless player was on.
Paranoid: If the Developer has become Paranoid, and is the target of the nightkill, then both the Mafia performing the NK, and the Developer, will die.
2. Oracle: No, the Oracle may not self-target.
3. CCTV Operator: No. The CCTV Operator sees if their target leaves their room overnight. They do not see incoming visitors.
4. Traitor: The Traitor is mafia-aligned. The Traitor effectively takes over as the Mafia if all the other Mafia die. Therefore the Town needs to eliminate the Traitor in order to win. The Mafia win when the town is eliminated - this does not include the Traitor and they may win with the Traitor alive.
5. Poisoner: No. It is possible for the poisoner to poison the Traitor.
