We do not know how big the scale of deception is. If campaign managers have purchased the account they are using to manage the campaign or if they have been caught using alt-accounts, then there is no reason they would stop their deception when they have ample opportunity to deceive their employers.
I guess that such things happens, probably not every person who runs campaigns is fair. But I doubt that happens at big scale. I just have nobreasons to suspect one or another member. Maybe it's not good thing, but I tend to have good initial opinion about people.
