In many of the privacy policies, I noticed there is one section as a disclaimer mainly talking about "our websites contain links to other websites, and it is your own risk/responsibility to familiar yourself with the privacy policies about those sites".
E.g. quoted one paragraph of this kind:
Because a quite high percentage of privacy policies contain such a paragraph, it seems to be a common practice and seems to be caused by legal reasons.
I am totally unfamiliar with legal aspects of privacy, could anyone provide some insights on the reason why it is a common practice? Maybe point out which regulation/law requires such a disclaimer? Thanks!
