My website http://keralatourism.synthasite.com was rejected by google adsense with the reason, "Chat Site". My site is all about tourism in Kerala and about tourists attractions in kerala. Not even a chat room widget is nncluded in the site.
Is this some know issue with synthasite? or is it some problem with the contnent i host? Kindly provide me some valuable tips to avoid this problem.
Thanks in advance
