How to add gif animated pictures as avatar?
I already saw pictures like this here on other's profiles, but when I tried to add, it says it's not possible.
Those profiles have had the animated gifs before the security flaw was found. Animated images are unavailable because of the aforementioned problem.
The only reason you might see any animated avatars is because they haven't changed it since - and personally, I wouldn't if I had the chance to keep a relic of the past
