Hi there, not sure if this should go on SEO or on Copyrighting.
I was thinking on adding at least 3 lines, disclaimers to my texts but inside the story, not at the end. Taker per example adding "This texts belongs to XX at www. aaa .com" inside a div or span with very small font size in white text, so small you can't see it but when you copy it, it will be there. Sounds silly at times, not so silly other times.
People steal content... and they are lazy. There is no magic solution unless you put some GIF text there with watermarks. Anyway lazy people hate work and extra work. Some won't even check or correct the whole story they are stealing, many use copy and paste or bots to steal.
