Allowing falseclaiming like that does two things.
1. It draws out counterclaims. Let's say I (as vanilla town) claim I'm the cop, and that I found player A guilty. That may prompt the real cop to come out and say that they found player A innocent, so I must be lying. Even if I then retract my claim and the town accepts that, all I have achieved is outing the actual cop to the mafia.
The real cop has no particular reason to counterclaim in this example, just as town have no particular reason to believe your claim.
All the cop is achieving by counterclaiming is A) exposing the fact that you are presenting a different narrative to what he would have town believe and B) drawing attention to the actual cop at a time when apparently the actual cop doesn't want to out. Continued below.
Or if you're suggesting players shouldn't counterclaim when someone presents information they know is false that just gives more of an opening to lying mafia players.
That's a bold statement to give without a lick of justification.
Players shouldn't counterclaim when counterclaiming does nothing to help them (i.e. town), just as players shouldn't do anything else which doesn't help them. As far as I can tell, in your cop example you are trying to present a situation where being hard-cleared and outed as cop would be bad for the cop and yet you are acting as if there is any reason to believe or counterclaim against cop claims at this time. In such a situation, a far more likely outcome to a falseclaim is that the town remains incredulous that cop would out themselves in such an obviously disadvantageous situation. In the common situation where whether or not cop should out depends on reports, the lack of a counterclaim is easily and usually interpreted as a 'counterclaim' by a cop who is in a situation where it is suboptimal to out.
2. It gives the mafia players way more room to work with when coming up with their fakeclaims. You can come up with one fakeclaim then change it if someone contradicts it.
Yes, and? An arbitrary restriction is going to reduce the sophistication of play all round.
It's not as if town lack the ability to review your behavior and question your motives. If you behave in a way which is ultimately anti-town, you will be regarded as anti-town by an active town.
Let's take the old beginner setup which had a 50% chance to have a cop in it. Generally claiming cop as mafia was risky because there's a 50% chance there's an actual cop in the game who can call you out on your bullshit and force a 1v1 fight for the lynch. If town is prepared to accept retractions then I can just claim cop as mafia with no risk. Even if the real one comes out and challenges me I can just say "lol JK" and back off, having identified a key power role to kill.
So in your mind there is literally nothing suspicious about rolefishing out cop besides the fact that fakeclaims are a naughty, lynchable offense?
Or in a more complex setup like the old Paranormal games, a big part of being scum is trying to create a fakeclaim that has the least chance of being contradicted by what other people did as possible. Let's say for example I'm mafia and I claim I'm a rolecop and I claim I visited Player A on night one. Unbeknownst to me Player B followed me that night, and saw I actually went to Player C's house. If the town doesn't accept retractions Player B knows I'm mafia, and the only way I can get out of being lynched is if I can convince the town that Player B is scum and making up their result.
If the town accepts retractions, I can just revise my claim to say I went to Player C's house. I am now in no trouble at all.
A huge amount of power role generated information generally qualifies as "real information" in my book. Why would you be seen as town for trying to reduce the quality of information in the game at a time when there is actual information available to the town?
So what lying actually does is out the real power roles and allows scum to survive contradictions that would otherwise sink them.
Incorrect.
Rolefishing outs real power roles. Fakeclaiming is an efficient form of rolefishing, especially in a meta where very few players fakeclaim.
Contradicting yourself when you are trying to present a legitimate and coherent argument is hardly pro-town behavior. If you aren't trying to present a coherent argument (say, it's RVS, or some other time when there is relatively little information to work on), there is nothing wrong with contradicting yourself.
I don't accept the benefit you're claiming either - if nobody claims what their role is the mafia has no information about them anyway.
Precisely.
Infact, the best way to avoid having mafia develop any leads on PRs is to never post.
This is optimal behavior in some contexts, but understandably arises rarely on B12.
I think I've covered in the early posts why inactivity is anti-town, but basically your main goal as pretty well any player in a conventional game is to generate as many leads as possible, including by allowing yourself to be read. Fakeclaiming is
activity, which is objectively superior to inactivity at such a time where fakeclaiming does not carry an opportunity cost (e.g. confusing town).
Claiming your actual role but fake results could be acceptable in some situations but I don't generally like it because it makes you look way more scummy if you have to modify your results when a mafia member counterclaims your role.
It is the duty of every player to appear to be town. The goal of the mafia is, in brief, to have a member of the mafia be one of the two 'most town' players, or two of the top four, or three of the top six, etc. The goals of the town is to prevent that, by having enough town players appear more towny than the scum players that the scum are lynched rather than the town.
With that in mind, a falsified report, the purpose of which is to generate targeted activity (specifically, to generate reactions to the report claimed), is generally going to be chosen is such a way that the scum team (who know whether or not the report is accurate, whereas no other players except those mentioned therein do) will slip in some way as to whether or not the report is accurate.
