True, but if you read some of the hateful crap there, well, it’s obvious they are from the Daily Kos. I have talked to the Mods there, they said there is no way to IP block someone posting on a blog, but I thought maybe there was a way for me to find out their IP address, so that we could scare them off. They won’t be going away
Besides, you just might end up with someone who is not ethical and who will instead put trojans or key loggers on your machine.
You should know people who are in law enforcement or writing software for law enforcement, or possibly someone who has written software for the CIA and can get them to help you.
I do know it can be done because I have read stories about those who have tracked people this way. However, I can't remember any names. Only the story.
Talk to some of your contacts. Much safer.
The problem with IPs is that if they have a static IP, like myself, then every time they reboot the modem/restart their computer, the IP will change. The first numbers of the IP give their country code... but in order to block their IP, you would have to block the whole country.
Also, you must consider, that they may be hiding behind a rounter... and if they are, there is no way an average citizen or even MOD/ADMIN can track them without bringing in Federal level law enforcement.
