No this isn't posted in your community, but your community is part of the Hive ecosystem.
@stekene is well aware of what he's doing, he has been tagged already. If it is bought to your attention that your curator is plagiarising, hopefully you will reconsider whether he should still be curating for your community, otherwise it would look like you're endorsing plagiarism on Hive. It's not the first time one of your curators has plagiarised.
