When posting content that either is owned by someone else or inspired by someone else’s works, it is proper to list the said source in your post with a link to the original.
Failing to do so is considered plagiarism, and could result in being blacklisted by curation groups or even flagged.
Examples include:
- Using another artist's original drawing/painting/digital art as a “study” or inspiration without linking the original and giving credit to the original artist.
- Linking to someone else’s YouTube video with no source.
- Using someone else’s photos or text without linking to the original source etc.
