Yeah, scammers are always on the prowl.
I have seen my good share of scams too.
Someone pretending to be from my brother's bank had sent him a text asking for his credit card number with the reason it had been blocked. Poorr innocent boy sent it and your guess is as good as mine.
Their activities are increasing daily thanks to sites like Craiglist.
I wonder why one would so badly want to steal another's money, but apparently these guys dont give a f*ck.
