Everyone knows plagiarism is wrong. Amongst sins, it ranks somewhere between kicking your dog and peeing on the toliet seat. You just don’t do it. I don’t care if the dog peed on the toilet seat. Don’t do it. We’ve known plagiarism is wrong since fourth grade when the kid at the next desk tried to pass off three pages of quotes from the Encyclopedia-Britanica as his own paper on brontosauruses. There’s just no excuse.
It’s not rocket science: Don’t copy other peoples work and make it look like it’s yours.
This is just as true in social media as it was in fourth grade. The whole thing is built around sharing and repeating other posts. This makes it easy to blur the line between networking and stealing. The retweet has been central to the success of Twitter. Facebook includes a Share button on posts with links, photos or video. Sharing is a core component of the social aspect, which is why any of this exists in the first place. The bottom line is that sharing means more content. More content means the network expands. And when the network expands, people make money.
But even though more sharing means fatter wallets, networks have attempted to curb plagiarism. Facebook’s share feature credits the original author. The Retweet button, Twitter’s own default Retweet method, puts the original author’s username and photo in your feed.
So what does plagiarism look like on Social Media? The networks themselves are still changing at such a rapid pace that it’s hard to nail down a firm set of rules for what constitutes stealing someone else’s ideas. So here are three guidelines:
1. If it’s not your post, say so. Clearly. On Facebook use the share button. On Twitter, use RT, via, or the Retweet button. They are the acceptable methods for a reason. Use them however you like, just use them.
2. If you found it on another account, it isn’t yours.If you want to pass on a link that you found on someone else’s account, indicate that. On Twitter, it means using the HT designation. On Facebook, simply thank the person with @ tagging. Better for someone to find out you’ve enjoyed something they posted than for them to think you’ve copied their work.
3. Have original thoughts once in a while. It’s hard to steal someone else’s idea when you post your own thoughts and ideas. Just sayin’.
I should finish by saying that though I’ve seen this happen a lot I’ve never noticed it happening to me. It’s probably because I’m just not really that interesting. Or maybe it’s because the community I have connected with online just doesn’t have this problem. But it’s not the personal offense of my content being lifted as much as it is the offense to the entire community. It weakens the authority and authenticity of the social interaction.
And if you’ve plagiarized my work, I still love you. Just a little less. (Thanks to Josh for that joke.)
