I had a comment like that on my work. I deleted it after publicly roasting the commenter.
It's likely I'll fail to tell you anything you didn't already know, but they apparently have an Android app that has reviews mentioning their payment system not even working correctly, as well as a suspiciously high amount of 5 star reviews considering the depths they are willing to go to on the recruiting side of things(I thought poachers with spammy messages were exclusively the domain of Webnovel). Their app is by a group nebulously called 'STARLIGHT.DEV' and that group has two other apps that are very similar on their face to Novelstar, with their descriptions being written in Indonesian.
Honestly, their app's whole premise confuses me. Why would you offer a platform for writers to publish and not have a website for at least pasting your work into?
