This, everyone. This, this, this!
I can’t stress enough how much of a point he makes. Source everything you find yourself if it’s not a reblog. And if it is, don’t delete the credit!
To the people who do this: Please understand the immense effort an artist puts in with their work. For you to simply discard it, it’s so unfair. Crediting is so easy and quick to do, you’ll be helping the person out so much and it’s a win/win situation for everyone!
If you don’t know where the source came from just leave it as is. Just don’t credit material that is clearly not your’s even if its freeshare material as well.
