I don't know the identities of the masons, if they are truly masons. I do have a list of people the mafia apparently could not identify, and so far it isn't really matching up with our masons.
After clarifying, I think I can give you guys the biggest help possible and say that I am 99% sure the mafia have a roleblocker. For once you won't get a name because I don't have one, and I am not allowed to say more, but just heed that warning even if you don't heed any others. If I had to speculate I would say Jcakes claimed an ability he knew we couldn't prove and couldn't be scrutinized. After all, if he only claims to have results against town nobody will ever actually be affected and therefor he will never have to explain. This isn't an OMGUS either, this is a condemned man giving everything to help his town and his team.
