Online error correction and Russian chance

Today I discovered one interesting feature of the VKontakte network. Searching for Habra found that I am not the discoverer of this error:

Vkontakte cheaters
VKontakte: look closed photos

Looking at the date of publication of the last topic, I was surprised - January 1, 2009. That is, the error has remained until now. For a year and a half, people take advantage of the false opportunity to hide their photos and anyone can view them, and as it turns out, even if they are not friends.

What is this? Russian maybe or simple irresponsibility?

I wrote to the technical support service - waiting for an answer.
