Soft Claiming is not only very borderline metagaming, but, it's also very close to game throwing at the same time. Hear me out before your OCD kicks in and tells you to correct my spelling, you spurge out and take 5 seconds to retort to a comment that took much longer then 5 seconds to make, or you just want to fit in so you monkey see monkey do everyone who disagrees with me.
When you soft claim, ask yourself something. Who is going to know that you soft claimed? A few people will know, sure, but, those people could just as easily be mafia as it could be village, and thus the reread comes in. If you are a cop and you soft claim guilty on someone because you can't out as cop yet, that person is going to know that you are cop and they are going to kill you, while other people will miss the hint and most likely reread later and miss it again because if they could understand that it was a soft claim, they would of understood it in the first place. The question comes to mind. Why not just hard claim? You have nothing to hide and the only thing you hide from anyone by soft claiming is the truth, while you randomly give only the players focused on you, the advantage. This metagame tactic makes it clear that a more skilled player will win more often, but, it doesn't mean that more skilled player is going to be innocent, which brings up the question; is it worth handing the game to someone through metagaming if you could be game throwing some games and not others?
Think about it, essentially being able to spot a soft claim will give more intelligent players proper placement in the leader boards, but, you are willingly game throwing fifty percent of the time by doing so if people catch on. It's like using inside language or code so that only your friends can win, and you are cheating in front of everyone's face yet they don't realize it. Some people like me associate soft claims with attempts to communicate with mafia partners similar to whisper, and only your partner understands it. Because of that, I would be more likely to lynch a person if they are soft claiming no matter what they said.
