IMG Management (which is not the same business entity as the IMG Management companies dealing with sports or models) made the mistake of spamming a board where I lurk and a board where someone in my family is active. Each of us visited the website the spam included and mentioned it at dinner.
The website sends out a dizzying display of red flags. No names, no location, no done deals, no client list, no qualifications...
It didn't take long to learn that the same note (IMG Management is a professional, affordable, full service option for musicians or bands seeking representation. Visit http://www.imgmanagement.com for more information.) has appeared on an amazing number of music boards, mostly local or dedicated to a particular kind of music.
Now they've apparently expanded into literary management, targetting screenwriters, and some of the people at IMDb were busy tracking down a bit of information, including tracing the IP that one of the music sites shows along with the note. They're located in Saskatoon, Saskatchewan, Canada--a long way from the 90210 zipcode shown on their profile (required by one website before posting) or the "NYC" in another.
I didn't look around much, but I saw no responses to their spam-posts at any site I checked except for a few posted just today, presumably by someone who recognized either naive ineptitude or outright fraud.
If you see them, steer clear.
