It's reminiscent, perhaps, of the feel and motivation for Tumblr reblogs - and Tumblr continues to be vibrant by virtue of this culture: https://www.tumblr.com/engineering/189455858864/how-reblogs-... (2019)
Now, is driving attention and reputation to their site (in the broadest senses) part of a blogspammer/reblogger's motivation? Absolutely!
But should we be concerned about rewarding their act of curation, as long as there is at least some level of genuine curation intent? A world where that answer is categorically "no" would be antithetical, I think, to the concept of the participatory web.
