Tracking IP address

Yes, it is possible to do so.

A2K can save your ars while tracking your every move

primarily you must tell us all about the comment 'he/she leave ... in a site" (sic) i hope so

secondarily you must promise never to do it again

tertiarily you must buy a new computer

quaternarily you must listen for the sounds of sirens and be ready to escape at a moments notice

It is also possible to keep people from tracking your IP address. The best way to do this is onion routing... and the best of these is Tor.
