The first rule of the internet is "There is no anonymity". This is an absolute, unbreakable rule that has been true every since the internet started functioning. The only anonymity provided by the internet occurs when humans are lax and discard or fail to keep records.

The moment you connected to this website the webserver logged your unique internet protocol address which is given to every device that's connected to the internet (in fact its impossible to use the internet without an IP address). The website immediately knows which ISP you used to connect to the internet and given the IP address, your ISP can track that address directly to your computer.

If you use a terminal at a library they know which terminal and security cameras can provide a photo, face recognition systems can match that photo to your drivers license.

Every email you send has your IP address attached to it -- by the email servers themselves. There have been a few (unconfirmed of course) reports that every single email and newsgroup posting is being monitored by the echelon tracing system set up by Australia, the UK, and the US. I don't think they can track all the in-country stuff (yet) but they can for sure track all the international stuff.

Every usenet newsgroup you post to has your IP address recorded (although most servers will encode the IP address nowadays so that the server admins can find your IP, but not the people who read the newsgroups). Most Western servers, that is.

Most people "fly under the radar" but if someone REALLY wants to know who you are, you can be found out, and found out far easier than you would ever dream of.

The bottomline is anyone, even the complete idiot, would be able to find out everything about you, even the good stuff that your mom doesn’t know about you.
