why am i seeing some kind of Oriental language instead of English in my Yahoo answers?

The posts you refer to come from spam bots, but one or more humans are programming them. They are being paid by the company they are posting for, to enhance search engine optimization for that company (or so it appeared when the posts began a month or so ago). We don't know when or if Yahoo will take action. All we can do is report them, ignore them, or leave YA. The posts are ALL OVER the site. Hopefully they will be dealt with soon. MANY questions have been asked about this already (it amazes me so few people think to check in the Answers category to see if a problem with the site has already been addressed). The site's been heavily flooded with them since the weekend of 7/7/18.

Yahoo never tells users about problems. Nobody knows for sure why it is being posted all over the site. To do something costs money and Yahoo is spending no money. They were originally spam posts in Chinese, now just junk. It may be spammers trying to get their web hits up by posting the subjects they are. It is thought their company name may be buried in the characters. It may also be someone who just does not like Yahoo.

Yahoo has been infected with spam bots

Drugs are bad, m’kay.

It’s just yahoo being incompetent of taking care of spammers.
