How posting online can get you busted UPDATE

UPDATE: Burning Black says that with a little work you can change your computer's MAC address as needed.

Recently, writers have been arrested for:

* showing throwups and tags on MySpace
* showing videos of their illegal actions on YouTube
* posting bombing photos to forums
* other people posting their trains on forums

The way this generally works is that everything you do online technically requires that the IP (internet protocol) address of your computer be recorded by the web servers at the sites you visit. Sometimes the IP address simply points at your ISP (internet service provider, for example: AOL, Comcast, BT etc.), but those companies can figure out who was doing what at a particular time, and web servers also record the time. So together, quite often, the webserver info and the ISP info lead straight to your bedroom. So if you have a local cop or reporter who hates you, s/he may do the work to track you down over the net.

Sites that care about your privacy, like Art Crimes, do not keep logs of user activity. Unfortunately most sites want to keep that information so they can count visitors and sell more advertising or simply have some way to ban some people temporarily from a forum. Some sites keep webserver logs forever and others dump them after some amount of time.

Google tracks everyone's search terms, for example, but now they say they will throw the IP addresses away after 18 months. But they have been forced to give massive amounts of YouTube logs to Viacom in a copyright dispute and this week won the right to anonymize them first. If those logs had been stored in an anonymized state they would not have posed the risk to millions of people that they did.

Posting copyrighted materials is illegal (expensively) and yet digging through everyone's records in order to find out who uploaded what is the wrong way to address it. Terrorism is terrible, but spying on everyone's phone calls in order to find the dirty dozen is not an acceptable solution either. Unfortunately the US Congress thinks this is fine and passed a law about that this month (FISA).)

My point here is that we all are being tracked by governments and media giants routinely, and that your favorite little forums can give you up by accident or through being forced to give up those logs they save. Your own equipment can leak information that's dangerous to you.

To get a bit more anonymity online, you need to use public computers or free wifi that you don't have to sign up for, but if you use your own computer or phone, it can still leave its own unique ID number behind (MAC address). Even your camera or camera phone can give up important info such as the exact location (GPS) and time and date you took the photo, camera type, etc., if you don't erase that info (EXIF) before you upload.

The best policy is not to incriminate yourself by posting your own illegal acts online, because technically, you may not be able to delete them, ever. Even then it's possible that someone else's posting of your illegal stuff will get you in trouble, so it's best to try to control what you've got out there and how it represents you, by restricting access to or usage of your photos. Same advice goes for those drunken orgy photos, of course.
