You always check terms whenever you plan to publish your work anyway. But luckily, they (webnovel) already amended their terms and services few months ago.
Anyway, another platform that I have yet to see being mentioned:
1) Tapread (its quite new)
2) Moonquill (Also quite new)
3) Scribblehub (if you're writing eastern fantasy, then this is your stop. Also, they are currently having an event with $200 prize pool)
Mangatoon... as a novelist, I have the worse experience. Their staff is the most unprofessional staff I've ever worked with. You can check my few ig post about my conversation with them:
