Well, it's not that bad. Allow me to inquire, how did you arrive at such a conclusion?
Nebo didn't write anything constructive throughout the game, but instead posted a lot of nonsense in the thread and added some distracting images. However, when someone was being executed, he quietly added his vote without explanation.
Lynx didn't do anything on the first day, although she pretended to express her opinion about the temptation to execute Yaschur, even though she had zero information about him. On the second day, she joined the execution of Tox when the situation was just starting to escalate, and then, it seems, the Mafia realized that they were all pushing for the execution of Tox and told Lynx to back off, or she decided to do so herself to avoid being exposed. After that, she remained quiet, but suddenly felt the urge to tease Yaschur. And to avoid looking completely detached, she replied to Krabby with a lackluster post, even though he wasn't even addressing her. Not surprising, as she might have to engage in a dialogue with a Mafia member.
Neira is the most ambiguous here. On the first day, she tried to portray the Ghost as not being a killer, but as a support role for the town. After receiving responses from Tox and Yaschur, she didn't bring up this topic again, and then she genuinely got involved in the game, started leading many discussions, and Tox even believed her. In fact, I'm not even sure myself, but no one else seemed to be playing the Ghost role.
Yaschur seemed like a town member to me on the first day, and he was active. But on the second day, he started acting strangely - he became less active, asked questions to the suspects, but only drew conclusions based on the answers. After receiving a negative reaction from Locken on the first day, he tried not to accuse anyone else, and even hesitated to join the execution of Tox. Although he clearly wanted to, he even outlined a plan on how he would extract information from Tox and use it against him. And another argument - the survivor can only attack those who visited him before, or those whose status he learned. So far, he hasn't made a single kill. Yaschur hasn't appeared in the newspaper even once, which is surprising, but it's possible that no one actually visited him. And he might have been waiting, or he might have focused on isolation/eating defense.
