Avoid Victimization

It seems the older I get the more scam attempts are made.  It is easy to fall prey.  A friend bought tickets from a scab site, costing nearly twice as much as regular tickets.  We get emails from paypal, etc. that appear to be authentic, but are not.  How to protect ourselves?  Information and caution help.  Do not click on any email link.  Go directly to the website if you are notified something is wrong with your account.  Chances are there is nothing wrong, and you would have been scammed.
