I am neutral (maybe partially for) on removing signatures in the reputation board as it is a fair argument to say that it might encourage responses.

However, I posts in the scam accusation board should remain as is. After all, posts there raise awareness for ongoing scams - new posts help the thread get indexed.

Both of these boards should be motivated by genuine interest and care however I am sure we call agree that turning signatures off in either of these boards will naturally reduce activity (it's just the cause and effect of removing incentive for posting).

If a campaign manager wants to exclude posts in either of these boards, they always have that option too.
