Why do I see cats and dogs instead of people?

It is possible that you have turned on the so-called decent mode that shows animals instead of photos and videos with human subjects. If you no longer want to have this mode active, you can easily turn it off.

To get a conventional profile display mode again, you can turn off a decent mode in two ways:

On the main page of the site below, you will find the link to deactivate decent mode by clicking a button or icon.
You can also use a shortcut and press "Ctrl + B" at the same time.
After performing these steps, you should again see photos and videos with people as used to see.
