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

yes it OK, I see many sites using Urdu/Hindi Roman and adsense works on it.
You can see there are lot of adsense ads in Urdu and Hindi text also.
