It will be better if you can add the column to add the nationality of the advertisor to avoid the confusion in communication.

communication. language is enough. Nationality is totally irrelevant and discrimination topic.

The nationality of the advertiser is irrelevant in this context. Only people with stereotyped minds and those with racist and segegrative mindsets would want to know the nationality of the advertiser. If you want only people of a particular group or region to respond to your ad, say Indians or Filipinos, post your ad in Urdu or Filipino in order to avoid confusion in communication. It's as easy as that!
