Well, this way you can almost certainly identify the blocker, the mafia, or the redirector if you get targeted by them. That's 3 out of 8 chances.
On the other hand, if you're trying to identify the race, it's 5 people, 3 frogs. You can't figure out the mafia. In general, "human" doesn't give much information. And "frog" isn't particularly useful in my opinion.
If you're trying to figure out if someone is local or not, it's 5 locals, 3 non-locals. If they're not local, then they're a candidate for being the mafia; if they're local, then it doesn't tell you anything.
In general, paradoxically, I'm coming to the conclusion that blocking isn't any worse than checking. The same 3 out of 8, but the result is more definitive.
The only thing is that blocking is public, and those who are blocked are less likely to be suspected. Blocking your own teammate on the first night and clearing them would be beautiful, but we're dealing with social deduction here, not mind games at level 90. If they find the Barbarian, they'll just put a block on top of it.

В тихой однообразной жизни всегда так бывает: каждый отдельный день бесконечно долог, но месяцы и годы мчатся с непостижимой быстротой.
