he does run a small wedding-planning business with a small team under him, I've confirmed that and for myself and have no reason to doubt it. I agree that it's very unlikely he's taking these pictures himself but I would argue that he does have permission to republish them.
a lot of the images can be found on the web as various location-catalogues on the web present those same images as uploaded by the venue operators, too
really though, I don't even see why that matters so much, the behavior of squatting a variety of trending categories with this minimum effort "original" content via bid-bots should be enough reason to flag his content and ultimately blacklist him from the bid-bots
this really isn't so much an issue about copyright as it is about abusive behavior towards the platform's twisted economics
