A lot of time added automatically!

Hi!
I was playing black and at move 5, I suddenly got a lot of time added without any reason, in a 15-second packet! I do not know if it is a server bug or if the other player was doing something! Here is the game:

Your opponent chose to voluntarily add time to your clock.

Owwo! I was not aware of that functionality!

If you want, you can deactivate:
lichess.org/account/preferences/chess-clock#giveMoreTime

In short, in the game there is a blue icon that, when clicked on, will add another 15 seconds to the opponent.
