scammer PM'ed me, asking if I would sell, asked to get low level access to check audience, I know it was a scam but got really curious, because it was really low role access so I thought "what kind of damage can he do really" to myself.

It was small page so I went with it, granted role (I will not go into specifics for obvious reasons) and waited... as soon as he got the role, he (or maybe someone helping him) claimed my page from another account and confirmed with this newly granted role by me, quickly removed me and merged it into bigger page.

As I was looking at it I actually managed to click "Cancel" button several times when he was sending claims and made it as troublesome as possible but eh.

It is a loophole that Facebook has not closed yet, I tried to inform them but tools are really rare for that.
