And the mafia is usually in an unfavorable position when many things are allowed in the notes. Because it's a priori more difficult for them to write a plausible note, supposedly from the investigator, than for the investigator himself. Although there are two ways:
1. Lack of competition – the investigator "sleeps" or is killed, but the town misinterprets the newspaper and doesn't realize this. But this is situational, and the second situation is only possible for Revan.
2. A huge number of notes from the mafia, like 10 from just one investigator. Then the chances that the town will find the correct one are small. Most likely, everyone will just ignore these notes. The problem with this method is that only Tox and I use it, which means we don't use it anymore so as not to be exposed.
