Using preview for after effect template promotion

Hello this channel promotes template after effects with our preview in the background with watermark. I asked him to at least put the composer credit but without success.
In addition its ENVATO links do not work. Unable to find his account.
What should be done ?

I asked him, does he have the right to preview models on YouTube? he replied: As I know, ENVATO has an affiliate program for anyone there that we can share without removing the watermark.
thanks @Manriquedelara @BenLeong or @KingDog to provide me with details.
