Innocents vote innocents all the time (seeing as with 30-some odd players in the beginning, chances are it would happen) and mafia will vote mafia...if anything being an OMGUS player is more scummy. You would rather jump on whomever attacked you rather than find real suspects to place a vote. Its a subtle way of being defensive...You think I'm mafia, so I'm going to vote for you even I have no shred of evidence that you are mafia...I'll admit thats kind of what I did with Ogre, granted I thought his play with mafia-like at the time.ICE, the only two people who voted for me that I think are mafia are Noods and Pappy.
I also think Zaffy is mafia have all along but he hasn't voted for me. I think you are suspicious but not necessarily mafia.
There are 6 people who have voted for me- I think two of them are mafia- the other 4 I don't know about. I think Ogre is most likely not Mafia. I think JM is probably not mafia but I don't know- I think his was more of a bandwagon vote- I was the current hot suspect.
I do believe somewhat in the OMGUS philiosophy as being a very basic and poor guideline but better than nothing. In that someone guilty is more likely to vote for you than someone innocent... guilty people knowing who are innocent are more likely to pick an innocent person than an innocent person is- even if purely random.
Anyone who is innocent who gets a vote from someone somewhat randomly from another person should consider that that other person could be guilty. It's common sense.
I can see it being used day 1, but day 3? Come on. Actually do some work rather than call foul whenever someone questions or votes for you...
