There were two emails and first was received on 31st of May and the second on June 1st. The first message appeared quite amateurish in its nature and has stuff in which some warning flags were raised.

In all these cases, the partners were given some details about the problem that was occurring in their account. The problem occurred in videos that had copyrighted stuff, bullying, hate and other such issues which were violating the ToS of the service. In the first email, YouTube partners were urged to reply with their password, username DOB, email address while in the second one the partners were asked to provide only their password.

It is not clear yet whether these messages were limited only to the tipsters or it was a real rife problem, but no matter what the case really is, YouTube users have been alerted and many are still waiting for getting a sound response. So, YouTube partners be aware of it and keep yourself focus.
