Credibility definetly counts. A lot of people, especially those who are unfamiliar with sig selling, will associate the poster with the program and if they dislike the poster, they'll steer clear of the program.
Not to mention, if the person has questionable credibility, then people will not be happy with you giving money to this person. Say, for example, Poster ABC had ripped you off for $300 and you see Company XYZ giving him $500 for his sig, despite the well publicized fact that ABC ripped you off. Would you sign up for XYZ? I wouldn't.
I'm not sure who the person is you're talking about, so I'm not sure what the credibility issues are. Just throwing my thoughts out there.
While we're on the topic, my sig is for sale
