Just threaten them on day 1, point out how likely you are to be the candidate for night 1 doccing and watching. Or go the full route, we both declare it's irritating to know that if DF, we're absurdly likely to be copped on the first night, and if town we're likely to be NK'd, and it's a bit of a funbreaker and bad sportsmanship. The only way around it is to point out that both of us will be in future games and will have to view anyone who targets us basically on the grounds of 'simply a big threat as a player regardless of role' as a potential threat on those grounds and they will be far more likely to be lynched or NK'd. And that having said that, even if we don't kill said person they are a great deal more likely to be killed by someone seeking to cast suspicion on us.

"If anyone targets me for copping or NK on night 1 I will kill them at my first available opportunity in the future, and having said that I will definitely do this it massively raises the odds someone will kill you other than me because they can push suspicion on to me, nor do I have to fear your death being laid at my feet is auto-death, because it is actually more likely, by the same reasoning you used to target me on night 1, that I am a major threat in of myself, that someone killed you just to frame me, so I can risk a possible lynch." Says FT or Isaac.

"But that's not fair, you're holding a previous game against me, this would be a new game." Says Victim-of-the-Future.

"To the contrary, it is the very reason for your action, you have targeted me on the basis of previous games." Says FTI

"But it makes strategic sense, I didn't have any clear targets and you're potentially very dangerous." Says VotF.

"I agree, but by that same logic it makes sense for me to say that I will reply in kind, and to do so to show it is not a bluff, may I refer you to the 'Mutually Assured Destruction' and 'No First Use' nuclear strategies. It makes good strategic sense to target me on night 1 when there are no clear candidates, I know it's not personal, if anything it is a sign of respect, but I am a strategist, if someone has a good strategy I must either concede defeat and realize I will rarely survive the first night and the game becomes boring, or I must make this good strategy a bad one, so people do not wish to pursue it. So I must threaten to retaliate and I must make it abundantly clear it is not a bluff, it then becomes a bad strategy."

VotF, "Makes sense, by why not only Night 1 NKs, why copping too?"

"Simple, if not stopped it is a threat to me, and not just when I'm a DF, knowing that I will be copped on night 1 means I die almost assuredly any time I'm a DF, but it also means that when not a DF the DFs have a greater reason to kill me on future nights because I am likely to have been copped and have probtown status. After all, who if they copped me guilty would not almost immediately proclaim it? Therefore I must ensure that targeting me for any night 1 action that results in my death or my alignment being defined is a hostile act. Anyone complicit in that strategy must be killed at the soonest convenient chance to prove it is not a bluff or killing/copping me remains a good strategy, my only logical strategy is to make it clear that it is not a good strategy." Says FTI

"But then we can never target you, that's unfair!" Says VotF.

"Not all, you can never target me when the obvious primary motivator and reason was that you see me, the player, not me, the current character, as a great threat. It will be hard for me to ever view any early night action as anything but a qualifier, I suggest you keep a clear NB record of why you targeted me for this-game specific reasons if you choose to do so, even if I was selected randomly so that you can prove it wasn't 'me the player' that was the target. That way I can say you are not my VotF without having anyone doubt that the policy is still in place when you don't die." Says FTI

"What if other players object to this policy?" Says VotF

"Unlikely, they too can see the logic of it, and must understand that if I am targeted for night actions a disproportionate percent of the time I am under a heavy handicap for play and may eventually have to quit, I tend to be viewed as keeping the game interesting, so they are unlikely to take issue with either the logic of the VotF Doctrine nor ethics of it, there too, they will be glad to see the doc freed up from the expectation of having to protect me and the knowledge that if I die their RC as a protective role will be viewed with doubt as either lying or fairly poor tactician, hence a good kill or a small loss if telling the truth. By doing this, I actually improve gameplay, because we remove a predictable pattern of 'Everyone target me on Night 1', and few will argue the point even if they disagree since they'd realize that just saying they don't accept the reasoning would have to make me view them as a greater threat." Says FTI

"Wow, FTI, that makes a lot of sense, how'd you think it up?." Say no-longer-VotF.

"Hey, the best defense is a good offense, and I wouldn't have to need a VotF Doctrine if I weren't a good strategist, would I?" Says FTI

So, basically, if you want to avoid this constant cycle of you and me getting whacked, copped, or lynched on general principle you just say something along these lines before a game starts... like this I suspect a lot of people have guessed I might have such a policy to begin with, due to the insanely high rate of casualties of those who have targeted me for lynch or NK, IIRC no one has survived a game they voted for me (even a lot of the people who jokingly voted for me on day 1) or died early in a game after trying for a NK on me in the previous one, though that was not usually my reasoning at the time.

Anyway I formalize this Doctrine before returning to play and offer it to you for use to since you actually get it worse than me and games are less interesting for me when you're not in them. Besides, nobody else besides us currently is a night action magnet.
