This is a sad, interesting, and kind of ridiculous story!
Some people are so commercially-minded, but I'm not convinced that they get ahead with this approach. So much care to prevent people seeing things "for free" just means hardly anybody sees them. Just my 2 cents. This "Forbidden Mountain" guy could probably make more money by writing a front page summitpost article with the most gripping chapter from his book, and discretely mention that he'll guide you up Ushba at the end. Right? But nope, instead it's all about lawyers and permission and ceasing and desisting.
By the way...
The "Summitpost Bulk Uploader" has a "Bulk Detach" feature, originally requested by Gabriele, but I don't think he ever used it. Perhaps an elf would like to use that feature. Send me a PM if the documentation page is insufficient and/or if you want to use it.
