Other schools are now starting to claim that Bristol GS are planting fake posters on this website as a way to drum up business.
That's the stupidest thing I ever heard (read, I mean)
In fairness, I think you maybe referring to the recent and infamous punch-up thread. What the person (school) in question was asking was why are there so many people who praise BGS on this site. Some read the surrounding text as an implied accusation that there are fake "BGS is wonderful" posts. This was not actually claimed by the person (school) in question, neither did I think it was intended. But like all gosip it has more inertia than a depleted uranium anti-tank round.
