"Dear PayPal User, Today we had some trouble with one of our computer
systems. While the trouble appears to be minor, we are not taking any
chances. We decided to take the troubled system off-line and replace it
with a new system. Unfortunately this caused us to lose some member
data. Please follow the link below and log into your account to make
sure your information is not affected. Account balances have not been
affected."

It goes on to entice users by saying that: "If fees would normally
apply, you will not pay anything for the next two incoming transfers you
receive" because of the inconvenience of having to re-enter data.
