Great article, Zack, I really get ticked of by Chinese automated hacks, and also do not care about SEO for those countries.
I believe Google has a local server in each country anyway, and I don’t really care about other search engines.
My content is for Australia only and I do not want business from any other country, as I for instance will not go and fix someone pc in another country!
Blocking 99% of the problem, gives me more time to patch the other holes in systems like WordPress…
Hope to see more articles from you.
