Whether or not that "publicity" is good for me is something that is mine to assess, and I have assessed that it is NOT good publicity at all. It's good publicity for the scraper. I had lost about 10% of my traffic prior to DMCA take-downs (over 5000), and this was recovered after the content was removed. THIS MAY BE COINCIDENCE. But that's the data I got.
Crowdsourced scrapers aren't hot-linking, but uploading to their servers. They are not bots and aren't bound by bot conventions. Hotlink protection and robots.txt aren't going to help.
I am curious about your trivial prepended script - I'd very much like to know how this is done as this give me something that I have to do once for each of my 20 websites every time I find a new crowdsourced scraper. It's a nuisance, but it's more within the reach of reasonableness.
