There’s definitely a few scams around PayPal. I had an e-Mail from PayPal a couple of weeks ago:
Dear PayPaI member,
We need your help resolving an issue with your account. To give us time to
work together on this, we've temporarily limited what you can do with your
account until the issue is resolved.
We understand it may be frustrating not to have full access to your PayPaI
account. We want to work with you to get your account back to normal as
quickly as possible.
What's the problem?
We want to check with you to make sure that no one has logged in to your
account without your permission.
Please take a moment to confirm your profile and/or update it.
Make sure that your account information (address,
phone number, etc.) is accurate so we can have your PayPaI
account issue solved as quickly as possible.
There was a link asking me to Log In and reconfirm my bank details. Needless to say I did no such thing and have used PayPal perfectly well since.
