Calling on my blogging friends to advise me. Several years ago, I posted a picture on a post which I found googling. The photographer has contacted me, demanding that I remove it. He has sent an invoice and claims that I infringed on copyright.
He has begun to harrass me, sending several emails a day, threatening to report me for copyright infringement, and listing the penalties.
I deleted the photos after his first request.
Is this a scam or an unhinged harrasser?
