There are merits to it, but there are also drawbacks.
While it is a decent way to prevent scum from, in advance, figuring out night actions, the tradeoff is that, so much as after a single night, it makes it
much, much easier
for them to PR hunt. In other words, it has an upside for a single night, but past that night it will cause the town PRs to be manipulated and destroyed by the scum in record time.The reason for this is, that if you know you are scum, and you know who else is scum, and you know who every player claims they targeted, even without them claiming the type of PR, you instantly are positioned such that based off of the town players' reactions come start of D2 (especially in comparison to D1!), they are revealing to you what they are and are not.
In particular, the latter is devastating on the town. You might think scum knowing what you
aren't
even if they don't know what you are isn't as bad as them knowing what you are, but the scum have more information than the town to start with (they know what roles THEY hold, and off of what roles THEY hold can reasonably setup spec what the town has fairly reliably) so knowing what you aren't helps them narrow in on what people ARE.
