@HBE, you are absolutely right about the $.04 royalty on statements. Last year, I analyzed 15 years of sales from one prolific stock shooter, and from 2003 to 2017 the average price-per-sale went from $117.00 to $7.41. The license types were 85% RM / 12% RF / 3% video.
I also agree that agencies no longer seriously apply the "3x the usual fee" price for violations that we set as an industry standard for stock in the 1980s. That language was clearly listed in every delivery memo and invoice, and probably still is, but it's ignored. Earlier in this thread, I mention Permission Machine that digitally tracks violations and attempts to collect fees on behalf of the photographer for a percentage of the amount collected (and there are several companies doing the same).
As a test, I ran 57 of my blog post images through the machine (which is based on Google's reverse-image tracking software) and was quite surprised to see the many violations. Of course, most were not worth the time and effort it takes to track down the responsible person and collect. The systems are focused on identifying cases that the company is the most likely to recover damages from / sell licenses to.
The "remedy" for the violator is typically to just remove the photo, as a DMCA Takedown notice gives violators a chance to do. The DMCA includes the "safe harbor" provision which protects websites from taking blame when it comes to copyright takedowns.
If thumbnail reference images (served up via link to the original) could be tracked so the photographer could be paid for display usage, that would help. We see this constantly when an article's featured image is shared with the snippet via social media. But since the user isn't hosting the image, case law has ruled that this is not copyright infringement. And the publisher, who paid a flat fee license for a single article usage, is not paying the photographer extra for those impressions.
BTW, I know many of the original Tony Stone photographers (Darrell Gulin, Art Wolfe, Frans Lanting, Stuart and Michelle Westmoreland, Tom Bean, and Bob Daemmrich come to mind) so I'm sure we have friends and colleagues in common! Welcome to Cake!
