I've just got an email from Shutterstock with a "content removal" title but then the body of the email is the "your latest payment... ect" message, but without any data on it (and all the images broken).
Did anyone else had received this email?

Yes, I got it too - I just deleted it, as no data was in there.
I suspect it was just a very poor scam attempt, as the email also had an inappropriate subject line.
