Cool! I particularly find the domain blacklist interesting. What prompted you to add the blacklist feature, and what sin did dolphin-emu.org commit to get themselves on it? Unfriendly to scraping, maybe?

What can sites do to avoid getting on the blacklist in the future? Were they non-compliant with some standard, or just too complicated to handle today (but you'll fix it later)?

Also, whoa, this is 5 years old, why is it being submitted now? Might be worth throwing a (2013) on this.
