If you want to share the idea, you must do something with it beyond copying the post and pasting it, there must be a contribution from you.
Because otherwise it is simply plagiarism
Because nowhere have you placed in your post that these are not your words, that they were copied from elsewhere, it is the creation of someone else, it is not yours.

Another thing, that post appears in different web pages, copied by different users, I don't think it was a very smart decision to upload that post.
