Fair points. I'd advocate for some labelling to indicate that it's a repost and not true OC. I didn't do a broader search into the user's behaviour but looked at the community quickly and they've been the only one posting content here for a month.
I haven't read them yet but it looks like there's more comments on this post now. I think interaction within this community, even without the reddit OOP, provides the value for me to differentiate it from slop i.e. pull it out of reddit and (presumably) real people are discussing it.
