Tracking IP in Nepal is quite difficult, dont know how it is in other countries. Here in nepal ISP need to be cooperative, most of them are not cooperative though, but since we all have some friends in all ISPs we maybe able to track them. Just becasue there are friends, we can break the policy of the ISP and take revenge on people after finding their IPs through those friends? Can't we just play by the policy and rule in place rather than looking for revenge all the time? Afterall, we have not seen any threatening emails or comments.. so Umeshji, you should publish all those emails and comments, just don't delete them. It's up to Readers who will analyze those emails and comemnts. Otherwise your web blog might be considered as just a propaganda.l
