Sinaweibo redirect wikimedia crawler to login page called "Sina Visitor System", whose domain is passport.weibo.com .Thus, when adding a weibo.com URL, the title is always "Sina Visitor System"(wrong). I hope the automatic system blacklist the domain weibo.com and always let users to manually fill out title, dates, authors because Sinaweibo won't allow bots to do that.

I think banning subdomain weibo.com is enough. m.weibo.com (mobile view) doesn't redirect crawler.
In mobile view it uses domain m.weibo.cn not m.weibo.com.
It's a typo. Sorry. Subdomains may have some other useful information, which should not be banned. So, only one is enough.
