My most recent one, which was two weeks ago, includes two old posts that ran back to back. It has somewhere around 1000 words and at least half of which was new commentary describing what I was actually doing. It was like a making of article in a way; a step behind the scenes. Remember watching movies, then watching the movie with commentary from the director, producers, cast? That's using the same content twice. It's commonplace in this world.
Artists and photographers can use their images more than once. I've seen the same damn images being used in memes countless times, nobody calls that spam. I've seen the same damn Pixabay images being used all over the place in numerous blogs, nobody calls that spam. I made my own damn image database with thousands of images that's free for me to use, so I will use it.
Bottom line: We're allowed to use our work more than once. The folks doing it irresponsibly are only shooting themselves in the foot. It's not my job to hold their hands and teach them how to run a blog/vlog or anything responsibly either.
I think this is something relevant too. I think you see words as supporting your images, I see my images as supporting my words.
It goes both ways.
