Hi, totally didn't forget about this :)
Some info which I think could be pretty useful: the OP mentions that there might be abilities that punish claiming. Cerulean is a Mafiauniverse player and setup designer and there's a pretty standard setup mechanic there called "anticlaim" which fits that description, which I'm familiar with due to playing on that website a lot.
Generally, the mafia team submits a post containing a claim, and depending on the setup and the degree of information (role info almost always counts for more than character or flavor info), the player who gets "anticlaimed" can be:
-rolecopped
-roleblocked (most common, usually for partial claims)
-killed (pretty common way to punish full claims)
-strongman killed (less common, usually in role madness games with lots of town protective roles)
So I would discourage claiming any info unless it's absolutely necessary.
