Do I bear the sins of publishing a video mocking others after reaching puberty, knowing that I had not reached puberty when I published it?

The signs of puberty are three: the emission of semen with desire, or the growth of coarse hair around the private parts, or reaching the age of fifteen lunar years. If you have not reached puberty, there is no sin upon you, and you should accustom yourself to acts of obedience and avoid disobedience; because for a discerning child, good deeds are recorded for him, not against him. If you have reached puberty, then you must turn to Allah with sincere repentance, forbid evil to the best of your ability, and strive to remove the effect of mockery. If you are unable to do so, there is no sin upon you.
