Sorry, but Epic really needs to step in and resolve these IP (Intellectual Property) issues by taking down the offending content.
As the platform’s operator, it’s your responsibility to manage such situations.
Ignoring the problem cannot be in anyone’s interest.
I want to emphasize that it’s unacceptable to allow violations of intellectual property rights on a platform owned by Epic Games, expecting the rights holders to act before Epic does anything.
This approach could adversely affect all creators in the Fortnite Island Creator Program.
