Not really related, but I personally don't mind any Chinese/Korean addon sites rehosting (clean) addons, since in general their userbase isn't proficient in English, and the addon description is mostly translated into their native language ..
Edit: Referring to sites like
http://wowui.w.163.com (chinese) and
http://wow.inven.co.kr/addon.php (korean)
Please don't target such sites >.<
