You've no doubt seen the commercials for the "free" triple credit score reports, or the "learn to work at home" packages on TV. In most of these cases, a URL is provided in the ad for you to visit. For the observant among us, note that the URL changes. Most often, a number appears at the end. For example, workathome.yes.you.can might become workathome58.yes.you.can and then workathome132.yes.you.can. This observation leads us to our Internet Safety Tip of the Day:

If the URL in an advertisement changes on a regular basis, you should stay away!

Especially since those "free" reports will actually cost you $30 a month.

This tip brought to you by the Internet Safety Council, the letter D, and support from viewers like you. Thank you.
