Usually Yahoo for me is the most trusted campaign manager here. The guy has like 3 or 4 campaigns every month in the bitcoin market alone. So that tell's how reliable he runs a campaign and we didn't know how he can managed those campaigns. Next I saw is Edwardard, who is also busy every month running campaign as well, been with him when I was a Member, if I'm not mistaken. Of course there is Darkstar, who is my current campaign manager. Lauda, who runs the Bitmixer campaign like a boss and I have the privileged to worked for her for more than 6 months in that campaign.
There's nothing like "the most trusted manager" you either trust someone or you don't. If all of them were honest and reliable with their previous jobs, all of them are equally trusted. The fact that someone has run 5 campaigns already and someone else only 3 doesn't make much of a difference.
Lauda is no longer running Bitmixer. How do you know Lauda is a girl? I haven't seen him/her admit to being a female.
