I feel this threat is very real. The DDOS attack here made me think that if you are sick enough to think scraping content is fine you must be sick enough that hacking, DDOS attacks and bombing forums with spam posts are fine. Rather be safe than sorry they say. At least have the info available, just incase.
Just like to add. That I am adding ASP code to my sites redirecting visitors from israel to a page restricted by my robots.txt page. I did the same thing years ago for russian visitors as well, but lost the code, sigh…
