There are many tools to ***** your IP address in chat, Facebook, twitter, etc. So you should be careful when chatting people. Once they acquire your IP address there are websites like [URL="http://www.ipaddresslocation.org/"]ipaddresslocation.org[/URL], [URL="http://www.ip-details.com/"]IP-Details.com[/URL], etc which will display your location when an ip address is entered. Please be careful while chatting.
