Crazy. I wondered if something like this might ever happen...

Fellow Yelpers were initially skeptical about Sean C.'s claims in this Yelp comment thread until he produced apparently authentic screenshots of the owner's angry private Yelp messages to him, and until a Yelp admin weighed in to say "we're here to help Sean out in any way we can... there's no telling how this person may have unearthed Sean's place of residence, but rest assured, that information was in no way.... provided by Yelp."

Sean C. never bought anything in the store in question and has an unlisted address which he never provided to Yelp, so he's truly baffled how the owner tracked him down. But track him down she most certainly did, the reviewer said in a series of posts:

 

Tonight I get a knock at my front door - I open it and a woman tries to force her way in... it seriously took all my strength to get her out.... and I had to wrestle with her on my front steps... was trying to pin her down incase she had a weapon.

Finally I was able to shut the door and call 911 - the police showed up and took her away.
