I noticed it happening at OTHER places, NOT just eBay!
Beware if its happening at Paypal, uBid or any other place used for commerce.
Then you know it is HACKERS and its definitely not bold to say so, all sorts of phishing scams are going around.
A BIG WARNING: If you get an email from Paypal or anybody, even Stormpay asking for your personal information do not even click on it!
Delete it and report it for phishing (law enforcement).
If you click on it, some people have been known to have viruses or accounts compromised.
Better to be extra safe than sorry for just not reading it right. Also one other issue you must look at....
When Paypal appears to be down during the day or night lately, and you login to your account and it asks you to update all your information and private security number etc etc....
DO NOT DO IT! That is most likely a part of a phishing scam. Even if its not, Paypal will never ask for that information. The only time commerce sites need your personal information, is when there is a dispute in progress and you have already talked to them on the phone.
Thank goodness GooglePay will be here soon with a hundred times better service, speed, and security for any business owner.
