(I'll try to keep it to the point...)
If you're not aware of the site WeHeartIt, I encourage you to head over there for just 30 seconds in the link below. If you do know of this site, then I'm sure you already know what I'm about to get on about.
It's full of things you might find on Instagram or Tumblr on a busy day. A few modeling photos here, some inspirational quotes there, someone might have posted some clothing designs, etc. You'll also find that none of the images there are sourced and hardly anyone cares about it unless they're the original artist. Many a time have artists tried to get copies upon copies of their artwork removed from that site, but nothing was ever done. Not even a measly little response from whoever runs the site. It's frustrating to have to see your own art get re-posted all over the internet and no one knows you created it because someone edited out your name/signature or removed the source URL. Sure, they've tried (I use this loosely) to make sourcing images a bit more favorable to content creators, but it never fails when someone re-posts artwork on another site and then along comes someone else who sends it to WeHearIt, thus continuing the cycle of lazy crediting.
Think of it like this: It's just as bad, if not worse, as if you stumbled across someone who took your artwork and re-posted it here on dA just because they didn't read the rules or didn't realize that dA is for posting your own art. Goodness forbid you encounter someone who posts things they like from around the internet and buck up on you for daring to call them out on their misdeeds...
Now, they only need about 900 more signatures last time I checked, so please show your support if you want. All they ask of you is your first and last name, a verified email account, and your place of residence. If you don't agree with the petition, then you don't have to sign it. Thank you for reading.
