When you sign up for something on the Web, there is often some innocent-looking text at the end of the form saying something like: "YES, I want to be contacted by select third parties concerning products I might be interested in." Quite often, the checkbox next to that text is already checked and your email address will be given to you don't know who.

Watch Out for Those Checkboxes
To avoid that,
- look closely at every form you fill on the Web and
- make sure all relevant checkboxes are not ticked.
Sometimes, the text will read: "NO, don't give away my email address," and the checkbox will consequently be unchecked by default. Check it.
