The standard in the hive is original content every time.
No recycling.
Plagiarism is the ultimate sin.

IF you set rewards to burn or decline for the videos not created and shared by the original author everybody will be much happier.

If you keep posting the videos of others and don't decline or burn rewards, that is an issue sure to bring out the mean in certain whales that care about this issue.
In order to show respect to the others that did this before you, we can treat you no different than we treated them.
That means that your rewards will be downvoted and your reputation will take a hit.

Please stop profiting from the works of others.
The 10% beneficiary is not a problem for me, you bring eyeballs to the content and that has value.
But, those videos by people that don't have accounts, and don't get set as a beneficiary, will likely see their rewards adjusted to the community norm.
Why would we want to reward somebody that can't be bothered to have an account with us?

Nothing personal, just business.
