This has come up a few times, so a reminder: reposting artwork/videos, or linking to unauthorized reposts, is against our instance rules! We understand that this is a habit for a lot of people, but let's do our best to respect the rights of creators so important to our community.
Instead, link the original source and support the creator directly! Need help finding the original link? VocaDB can help you find vocalsynth videos: https://vocadb.net/ And SauceNAO for art: https://saucenao.com/
