Facebook Page Likes Invitation

Is anyone know this method.
These days we are getting invitations from friend id or from our personal id to like a page.
Like i am using 8 Facebook ID's and i am getting notification that ...... and other 4 person invite you to like this page.
We didn't send any invitation, so how this is possible?
Anyone know about this?

Maybe it's a bug

What FB page it is? Maybe post here schreenshot of this notification, it could be FB bug someone is using.
