I have recently had fake 2nd chance emails to my ebay inbox. I knew it was fake as it was addressed to my ebay name and not my full name. I also checked with the seller who confirmed it to be fake.
I have also had fake warning messages re my paypal account. The paypal fake gave the impression that someone was using my account. This is clever as you don't think straight when you worry.
Never reply to them as you may be passing them information that they can use. Also never reply with your name!!!!
Paypal are great and are experiencing a lot of attempts like this. They work 24/7 and ask you for the email to be forwarded so that they can deal with it.
