Well, this is quite a conundrum, here. I can see something interesting bubbling up.
We've got two situations that occurred at two different times. To begin with, last night, I sent a few messages out, to a few people, with the permission of the investigator, to try to find out who is behind Lord Vader's mask. Fortunately, one of the four replied back as Vader, and he's been identified. I actually told vudu, because I had on good authority that vudu was a townie, too.
Now, then, since things worked so well last night, I decided to carry out the idea a little further: This time, the move was to be one at a time. I decided to send messages to players saying they'd been investigated, and turned up mafia. The idea would be I'd get one of three reactions: They'd say I was wrong, and ask why I'd do that. They'd say I was right, and actually give away a mafia member. The third is most interesting: They'd accuse me of being mafia myself.
Now, look at it from this perspective: If you're a townie, and you receive a message accusing you of being identified as a mafia player, you'd think either the person was vying for information or the person had a source that was faulty. However, what kind of mafia member goes around accusing townies of being identified as mafia members? What good would that do for a mafia player? It's not like a townie role would reveal itself after that, so clearly, the strategy choice would offer no competitive advantage, right? At least, there's not one I can identify.
Now, before, I believed Stratos to be a townie, with the off chance of being mafia. At this point, however, I'm not so sure. Like I said, even with the false message, assuming I'm a mafia member after it makes very little logic, and so I question why he'd vote for me immediately, without any deliberation. It makes me wonder, to say the least.
