Reps are faily given out, it's no surprise as he is the founder of SmG, and has been here for 9 years or so, members and users that come and go gives out rep to him and so on.
So having him the most rep member in SmG is no big news to us.
If you want to gain reps, maybe get to the good side of everyone's, then maybe you'll as much as Cloud does. No need to sulk about it.
Cheers
