> The word missing from the abstract is 'PornHub', of course. They're not just studying “a dominant online platform”. The fact that it is PornHub seems relevant enough not to hide it in the abstract to me.

The fact that it was PornHub is mentioned repeatedly in the paper itself. Leaving it out of the abstract seems fair—they picked PornHub because it was a site that deleted 80% of their content, not because they're specifically interested in studying PornHub.

And, they study several of MindGeek's sites, not just PornHub exclusively.

Sure, but omitting it is like having a study about 'a dominant social medium' and not mentioning that it is Facebook or X in the abstract (or a study about radicalisation of young men focusing on 'an anonymous imageboard' and not putting 4chan or whatever in the abstract). These are for the most part unique beasts, not interchangeable venues.

It is relevant information for anyone scanning through dozens of abstracts on the topics addressed.
