I have a website for short sms messages and jokes, the website is primely in English, however some sms's are in indian/urdu/precision and some other un-supported languages , is this okay with adsense rules? Am I getting banned for some short articles that are been posted by users in unsupported languages ? should I delete any thing that are not in one of the supported languages? Please help
I doubt it's a problem. I've had Adsense for years on sites that had some pages with content in non-supported languages. In the worst case, you don't have to delete those articles, just don't show adsense on those pages if you're worried.
