it's questionable but not uncommon on social networks. Lots of 'influencers' have content created for them. They usually execute getting the work done and using it in a much more professional manner so no one even knows it's not their own work.

That's not to say that the platform has to support it but be aware when someone who lets slip what they are doing is penalized, someone else gets away with it by being able to hide.

I'd prefer if there was transparency and then people could make their own choices if they are going to support the work or not.
