Dear skyshopindia,
if you happen to find a listing that you think violates policy of the marketplace, do report them to Contact us link. http://pages.ebay.in/help/contact_us/_base/index.html
Vigilant users like you help the Trust and Safety team in monitoring listing policy violation better.
Similarly if you will like to know about validity of a listing, the Customer helpdesk will be the best avenue to find an answer.
Regards,
Sapana
