You can find a conversation with that dude in my blog, either the deleted resteemed post or in my replies. It's his new business model, he said it. Today i got the reward for criticising his action, and had a look again, just to see he's making maybe 10 posts a day or so and at the 7 days mark all empty (most)
I think the motivation is either afraid of dmca, or too stupid to watermark his work if he's so concerned.
Thanks for your replies guys, at least i now know i'm not the only one not approving of it
