If you share the work of others, it’s your duty to make sure that the creators of that work get proper credit. Crediting work in our copy-and-paste age of reblogs and retweets can seem like a futile effort, but it’s worth it, and it’s the right thing to do. You should always share the work of others as if it were your own, treating it with respect and care.
What if you want to share something and you don’t know where it came from or who made it? The answer: Don’t share things you can’t properly credit. Find the right credit, or don’t share.”
