Just got another of those "You're infringing my copyrights. Take the image down or I'll sue"-as-a-comment-on-a-random-blog-post scam messages.

They're learning.

This time, they copy-pasted the DMCA boilerplate you'd send to "a service provider" like WordPress.com or Blogger (i.e. not the blogger themself) and you get to the download link without being asked to log into your Google account... but the "download proof" link is broken so I still don't know what the scam is.
