ya... as to how they track down the fellow.. I think its thru your URL address.. you know those... e.g 246.125.83.25.. every internet user has it own address..
the only thing is that it is VERY time consuming to track down who this address belong to.
first they find out who is the service provider..( Starhub, Singnet or Pacific) I think they are obligated to help provide the info to the police by law ..then thru their help.. track down who is using..
Thats why regardless whether the person has violated via emails or blogging..it is still not a problem to track them down..
Any one please correct me???
