Great that you liked the article.

You can post your old content here. But it might not be a good idea because duplicated content will be penalized by Google. Also I think Steemit should get unique content. Remember, you are saving on a blockchain forever. In hundreds of years people will still be able to read you stuff. Make it count.

But Steemit will not create a problem for you. No mater whether the Cheetah bot appears or not.
