Dear admins,

I received this email from paypal this morning.

Background:
- Email was registered with xda using yahoo address guard since 2010.
- Emails are forwarded to gmail account
- I am not an active contributor but i do frequent this site a lot to find info.
- My xda account details are not set to public
- Other services which have this email address is tapatalk

I believe the email is legit, as it has been signed by paypal and verified by gmail.
