Hidden Profiles or Locked Videos

I honestly don't understand the line of reasoning behind having a hidden profile or a locked video. You already know the type of website your joining plus the type of people who tend to frequent hell sometimes I find a good video and I just want to see if the person has more of the same. But more frequently I've come across locked profiles or password protected videos, If your that shy or embarrassed or even ashamed of them you can always hit the delete button. Some people have told me it's to prevent people spamming their videos when the most comments ive seen on the type of videos I watch are no more than 60 tops. But whatever if your not going to show the video whats the point of having It on the site. This concludes my rant....for now.
