Hi all, interesting thread and I loved the article above, it certainly makes you think about what's going on on-line.
However, and I am sorry to have to tell you all, this company are legit. I work for AFP, and have checked this out for somebody who was worried they may have infringed. At first I was suspicious of them, and their methods do seem to be a little amateurish, but I checked with head office, and they are being used to chase copyright infringers.
I can only presume the other companies they claim to be working for are also accurate.
Hopefully, armed with this correct info you can all choose your approaches from this point on.
I think you need someone expert in copyright law tbh,
good luck.
