I already replied to you and explained it:

The photos are the main highlight of the post, not the text (the text is scarce, anyway). They are published in an attempt to gain rewards (for monetisation). The user already monetised these photos on Hive before. In this case they are also submitted to the contest, so the photos being the main highlight of the post is even more obvious.
The recycling of the content refers not only to just text but also to photos, art, etc.

It seems to me logically obvious that content means any content that is submitted for monetisation, not just text.
