Is one who watches immoral clips or listens to songs online, even if they skip the songs and advise those who upload them to delete them, sinful?

If a person watches a forbidden video or listens to a forbidden song, they are only accountable for their own action and do not bear the sin of others who watched or listened, as Allah Almighty says: "And every soul earns not [consequences] except for itself, and no bearer of burdens will bear the burden of another."

However, if they contribute to spreading them or inviting others to them, they will bear the sin of every forbidden viewing or listening that they caused, as Allah Almighty says: "And cooperate not in sin and aggression," and as the Prophet, peace and blessings be upon him, said: "Whoever calls to misguidance will bear a sin equivalent to the sins of those who follow him."

Watching cartoon films is permissible with legitimate controls. If accompanying songs are heard unintentionally, there is no sin.
