Will it hurt to copy and paste articles?

After reading everything here, I have decided to not go ahead and copy over a bunch of articles. Thanks everybody for your input.

Ofc it would hurt.Original content is a way to go.

At least 80% of the article's content have to be unique or it will be considered as low quality post or spammy content, but you can rewrite the same idea of the article in your own words and create genuine content or you can spin the article that will replace the words with their relevant synonyms but they won't give as much guarantee as original and genuine content will provide you.
