But he's out here risking his reputation for this; he puts a stake in every one of these posts he makes. If the person turns out to be a total flake or whatever, Kage looks bad. If he were to start making that into a pattern, it would hurt his reputation (theoretically). So from Kage's perspective it's kind of better not to do this, or at least not to whore out every random plea for money you see/are asked to whore out. I'm sure he gets a lot of them, since people listen to what he has to say for whatever reason.
Maybe he's just learned that it costs him nothing to stick his neck out in this manner; given that it's Kage, that's very possible. Perhaps this guy is just a buddy of his or something...IIRC Kage was whoring for donations for 2 Gryphon's plane tickets or something a while back.
Kage is not an altruistic person. He likes to be perceived as such, but there's always something in it for him, even if it is just accolades. I tend to think he gets that enough anyway; so there must be another angle. Who knows.
