Well, what happened on crossfit was that somebody was writing up programs then inventing new names and posting what an expert this guy was...but, all the posts (and I understand it was quite a few) were all from the same house.
So, you can rip on places like crossfit or dragondoor or even here (T-Nation) for moderating things, but usually, it seems, people ask for it. I mean, really, what would drive someone to invent a bunch of internet IDs to support their own stuff? Why? It is not like you are going to make a ton of money posting your workouts on the net (trust me on that). Moreover, results speak for themselves.
So, when a site (like crossfit) bans somebody for posting a workout then posting a bunch of phony "testimonials"...I don't get why that is an issue.
