I have noticed this a LOT, with my resume dumps in the past, it is prudent to be aware of what you are sending. I spoke to one CP that says he has received all sorts including DOB, Creditcard, passport scans, Drivers license scans, etc.
personally I would never include a photo, full DOB, Passport or DL details (except "current/nationality")
personal total address should only be included if you trust the recipient, instead use suburb, city etc.
basically, be aware who you send it to, especially if the company is not reputable, the information you send should only be information you wold be comfortable with public access - not all companies dispose of the thousands of CVs they receive confidentially or correctly
