If you are selling stuff on Ebay or Craigslist on a regular basis, you might get approached by another seller with a request. He will ask you for help in order to boost his business.

He will be willing to give you a few hundred dollars if you can add his e-mail address to your profile as your secondary e-mail address He’ll say he won’t even need your password or login – just add his address to your info. He might come up with an explanation for the whole story, such you’ll get more credibility and the number of your sales will double if you have your e-mail address on two different profiles.

How to avoid: don’t add his e-mail address to your file, however attractive the few hundred dollars seems. Scammers came up with a way of tracking and logging into your account, by using their own “spiders” in their e-mail address.
