Just gonna copy and paste what I wrote on another NovelHD topic.
It's an issue mostly(or only) affecting Wattpad writers. As far as I know, Wattpad is aware of the issue and is working to solve it, but it's difficult because of copyright laws in the country of origin of the site. Mirror sites like this one and Truyen have always been a thing. It's an unfortunate part of posting online. Because of the complicated laws, it's hard to go after them. Hitting them with a DMCA doesn't work, people have tried, and they simply don't care. Pretty sure it would be the same with the petition. Some people are going after Cloudflare since they're apparently hosting them.
The main issue with NovelHD is that if you post a note on your chapter saying that your work can only be read on WP, it will change that to say it can only be read on their site. But I noticed they keep the pictures that are posted with the chapter (I posted memes and character art, lol). So I made a quick little comic about the situation and posted that at the end of the latest chapters. It made it onto the site, lol.
Also, I've been posting this because I'm petty:
Also, please be careful with visiting the site. Sites like that one can give you all sorts of malware.
