When does an owner get to tell a diner to shove it?

• Yelp
• When Yelp becomes yelling.

Yelp finally broke someone, and it came with the public outing of a regular person trying their hand at online restaurant criticism.

Fat City reader Jerry pointed me to an ABC piece about the owner of Boners BBQ (settle down, children) in Atlanta, Georgia. The owner, apparently frustrated by a negative review on Yelp, responded on Twitter and Facebook urging other restaurants to boycott the reviewer. He went on to allege that she had failed to tip her server and he posted a picture of her from her personal Facebook account. He later apologized, pulled down his rants and offered her a coupon.

Is this a restaurateur finally striking back at the anonymity of Yelp, or does it go way past the line of what’s acceptable for a restaurant owner?
