I'm sorry, but chopping block accusations are a really stupid thing to do on day one, without any actual investigation results or evidence present, imo. That pretty much only benefits Mafia in that case.
I'm sure you hit some nails on the head there, also because it's mathematically impossible not to, Juice, but come on...
First you say multiple times you aren't going to claim your role, but instead opt to basically say "I can't claim for the sake of Town" and try to make it seem you are important for town (which I can believe). You get (understandably) frustrated and annoyed about how you partly put yourself in the focus. Then, you start being passive aggressive about how voting looks and goes on posting multiple "last posts", while also suddenly do claim your, actually beneficial, role 3 fucking hours before deadline, when there is a big chance most players won't even be able to contribute anymore do to time zones etc.
And then you post your fifth or sixth "final" post, which is your personal list of what you think the alignments look like, with your only actual proof being that you know your role. You know that if we get to see you are what you claim to be, then everything you did and said is going to matter a lot, so why get possible Townsfolk into danger? ...and all that basically just for a possible personal "Told you so" moment when it might turn out you have hit someone scummy with it.
If you are the FBI Agent, then you still (inadvertently) helped the Mafia (at least for a couple of rounds) with it.
