That's true there should be a level of complication when designing a site to avoid getting duplicated there are so many fake Sinbad sites now because it is easy to copy the real one, I recommend WordPress there are some plugins that will prevent copying content.
It's good that the real
https://sinbad.io/en is now using Cloudflare this is to differentiate the real one from fake sites, I check some of these fake sites and they are not using Cloudflare at least for now but we never know.
For this type of site, I don't recommend Wordpress, and it won't even be necessary. What they need is to improve the website template, in order to make copying the layout more complicated.
In case they use Cloudflare, it is not too expensive for a hacker to use the platform. But they tend not to. Even so, for many users this element may even go unnoticed.
