I have  been robbed by them myself, but so have many others.

My paypal account was hacked about 5 years ago and paypal then stopped any  
further purchases. I then had to talk to the sellers to see if they would 
take  my check, telltof, led man, etc. I found that I can use another e mail 
account  and still buy via paypal.
