Beware of YouTube service spam email: If you receive any so-called email from YouTube Service. And the messages could be something like these:
“YouTube sent you a message:Your video has been approved”
“YouTube Service has sent you a message: Your video on the TOP of YouTube”
“Can I link your video in my blog/ website”.
Or some other messages. DO NOT click on the link. It will link you to a malicious website.
Just delete it.
