Staying hidden

Staying hidden isn't as easy as most people think, but it isn't hard if you know how.  Go ahead, check the whois for this domain.

Since you aren't going to do anything illegal, the only reason you would want to hide is so you can avoid getting on spammer's lists, and if you complain and get them shut down, avoid any nasty responses from them like we had from Agistment Australia - equa_properties@ihug.com.au.

Be very aware that many email services, such as Hotmail, include your IP number in the header. That, associated with the date and time is enough to identify you if you do something stupid. 

If you know how, have a good look at the email headers.  Your connection may go through a proxy server, in which case EVERYONE at your ISP has the same IP number which means you are untraceable.

But be careful, think before you click. Have fun, don't be dumb.
