Adsense and duplicate content

Hi,

I'm trying to get some websites approved by Adsense by scrapping Youtube videos subtitles. I've succeeded to get 2 sites already approved, but I'm struggling with the third one. Whenever I submit it I get rejected for "Scrapped content".

My articles all pass the Copyscape, but from time to time, when I search for some exact match sentences in Google, some other sites have the same content, but without any formatting, images nor links. It's just plain text. My pages rank all the time at the #1 position of the search results for these queries.

I'm wondering if someone here knows more about how they go about validating sites content. I'm sure they don't rely on Copyscape. Do you think that if I modify each sentence so the exact match requests won't show the other sites, will it work?

I've CleverSpinner, but I have a hard time playing with the settings to spin a text that doesn't require long minutes of work to make it readable, knowing that a human will review it.

Thank you,

Do you use any tools to scrape the youtube subtitles

Yes, I created my own. But there are some free tools online that can help you do this.

whether you success apply adsense after you use youtube articles recently,such as in 2019,march and April?

I was in your same situation. My account was approved by adding under article the source.But I'm afraid that, as YouTube is Google propriety, they can do what they want.
