Neovel isn't predatory. I've met one of the founders at least once, and several of my author friends use it. The site even had a Kickstarter last year.
They are, however, quite small, so don't expect many views from them. If you have the time, though, it doesn't hurt to post on. I plan to crosspost my newest book on there eventually, although not until much later.
I've done pretty thorough research on a lot of web fiction sites, especially the ones that do solicits to authors, and while I don't like it when sites try to get you to post on them without actually offering anything in return, they are NOT like Dreame/Webnovel/Ringdom/etc. scam sites, at least at the moment.
