Blackberry Messenger's account can be replicated?

This is from Indonesian article: "detik.com"
"Metro Police department: there are many Al Gazali groups victims, they often replicate Blackberry Messenger's accounts."

translation of some of the article:
The perpetrators replicate BBM (Blackberry Messenger) of victims by stealing email and password when the victims download something. Then perpetrators use BBM of the victims to ask for money to friends of victims.

"Jadi para pelaku menggandakan BBM para korban dengan mencuri email dan pasword, saat para korban mendownload sesuatu. Kemudian pelaku memakai akun BBM para korban untuk meminta pulsa atau uang ke teman-teman BBM para korban. "

I'd like to see more info. If someone gives up their login and password for any account, the account can be taken over. That's not an account being replicated. It's essentially being handed over.

Yeah, it's more phishing than any actual trickery.

No system is tamper-proof so long as there are humans involved.
