You are all incorrect. What you all experienced here was Internet "Phishing". The supposed emails you received were definitely fake. But the weblinks those emails provided were also fake, redirecting you to fake eBay and/or Pay Pal websites. IF you logged into them your account info is then stored on a server of the fake websites and YOUR ACCOUNTS WILL BE HACKED.
I highly recommend, IF YOU CLICKED THOSE LINKS to log in, to change your email AND your passwords.
Unfortunate these idiot spammers are able to do this, but eBay and Pay Pal tell you to NEVER to trust an email. Yes, eBay and Pay Pal will and do send emails... but never trust a link provided in one. Log into your eBay account to check for any messages there, and log into Pay Pal to check your account. Do this the normal way by typing in www.eBay.com and www.paypal.com.
Again, NEVER trust a link provided in an email... EVER. Especially when money is concerned. There are regular bank emails that are "phished" too, redirecting you to a fake site that captures your account info as you "login".
