So I was 3rd party scum (I know the scum team, I can't reveal who they are, I win if I'm last man standing along with the rest of them, but lose if I get limmed before). One of the scum team was an anonymous messenger who had to pick between three signatures for his messages (Chara, Gamma Emerald and Almost50 I think).
My gambit was to have him send messages to people going "I'm part of a parallel secret Boon game and you're my partner in it; I'm not allowed to tell you more but follow my instructions" and hopefully have people believe it and play according to that.
Although one of the targets misinterpreted it we did manage to get some chain lims set up because of how that affected their play. But Gamma replaced into the messenger's slot and trueclaimed scum messenger; and now that it was known that it came from a single slot rather than mysterious out of game players, it was obvious he was scum and he got limmed
