So we should believe the IRS does actually call people and ask for their information? Because if you think listening to these types of posts are the equivalent of massaging anecdotes into actual "data", that's the conclusion you're going to come to on either subject matter.

Or we could realize the fundamental ego-stroking absurdities of these posts, take into account there's no evidence, take into account that no employees former or current say that Yelp is involved with nefarious business practices, and take into account the business' own statements on this matter, and come to the very rational conclusion that these posts aren't based on any actual actions taken by Yelp.
