Mafia 101. Disputed Island

Yashchur, if you're right, it wouldn't be difficult to figure out Kosha's accomplice. We don't have that many people who could potentially use such tactics, and Kosha isn't one of them; her gameplay is more straightforward.

Okay, let's say Kosha, who is supposedly straightforward, is sitting at her laptop, drinking tea, and then Master writes to her in a private message: "You're a zombie."

She replies to him: "Let's recruit Yashchur! He's very cunning, unlike me, a simpleton!"

About 24 hours pass, and suddenly Yashchur is a zombie. And then he suggests to her: "How about I block you so that you can be hanged later, and I become USEFUL until the end of the game!" And Kosha says: "Great idea! I like it!"
(All names are fictional, any coincidences are accidental)

I'm getting at the fact that Kosha's supposedly straightforward gameplay doesn't rule out the possibility of her being a Mafia member. But if a protective block did indeed take place, then Yashchur is also likely a Mafia member. If you organize a protective hanging every day, or even every other day, the effect will be less pronounced, and everything could go wrong.
