Scams are now easy to do from the scammers front room. 

What to look for......

• Registration fee which include you getting you money back within a short space of time.
• They offer you the tools to earn but nothing more.  These could be software or packages or even ebooks.
• Investing a small amount of money in a form of pyramid enterprise.

• Are there contact details?
• Does it sound legal? 
• See if the site is registered, if you are able to find the businesse for example on Whois then you can complain, or if you cannot find them.....
• If you decide to buy from a site promising you a fortune then see if the check is secure.  Another indication to scams.
