I'm sure they probably are at some times. My only point was to say that there are situations where a statement from Yelp to the contrary doesn't really mean something isn't happening, with or without Yelp's informal approval, so it doesn't necessarily put the discussion to bed. It's just one more point of reference, and should be seen as such when people are making their own assessment of the situation.

Someone hearing complaints of Yelp coercing people shouldn't immediately believe it or believe it explains the whole situation, and neither should someone hearing Yelp's response. They are both possible insights into the actual reality of the situation, which may accurately describe part or al of that reality to varying degrees, and should be seen as exactly that.
