I don't understand why anyone is being hostile towards you and your event, it actually sounds kind of neat to me.
If you actually read the text on the poster thing he made up, it clearly states that it's a video of a team/person drifting, or creating some sort of narrative based around drifting. It actually adds a whole other dynamic to the competition side of drifting in GT5, rather than having a team battle or comp where everyone argues over judging lines/angle and stuff.
Instead of just shrugging this off and claiming it's a waste of time, maybe the drift community could be a little more open minded instead of acting like a crotchety old man set in his ways.
Also, it's pretty obvious the use of the facebook, HKS, Falken, and other logos is just to add a little detail and make it look a little nicer/professional. Clearly he and his team have put effort into this, why are you complaining?
