Please please please do not steal or repost other people’s content.
Whether it’s an edit, a gif, fanart, fanfiction, whatever it may be do not steal it or claim it as your own. Do not repost it without the creator’s permission, and giving credit without informing them that you reposted their content is not okay. If they see that you reposted their art without their permission (whether you gave credit or not) and they ask you to take it down, please do so.
Creators work very hard on their content to share with the community, it takes a lot of time and effort, so please be respectful.
Sometimes it’s hard to tell if the content is stolen, especially for gifs and edits, but the easiest way to tell is by the signature. Most people put their username or signature in their content, usually in a corner in small writing or text so it doesn’t take up a lot of space. If you see that the username/signature in the content is different from the one that posted it, it’s likely that the content was reposted. You can also check the blog itself, it’s usually fairly easy to tell if it’s the original creator’s blog or if it’s someone that reposts other people’s work.
If you find that someone has reposted someone else’s content, do not reblog it. That only spreads the repost further for more people to see. Instead, you can send the person a message and politely tell them to take it down.
Creators work very hard to provide content for us, and I’m sure it must be hard for them to see their work reposted. Please be respectful, and do not steal, claim, or repost their content.
