Ah yeah, that happens a lot, especially with new authors. Scammers will inbox you or comment some generic compliments before offering art commissions.
I looked up your account on the main site, and I see that you
just started. It's natural to not instantly become popular. Fret not, webnovels often take some time to take off, especially if they're not some of the more popular genres. Additionally, readers like to binge when they see a lot of chapters published (usually ~50+, if your book is gonna be that long), or the book is already completed. Just keep writing, have fun, and don't compare yourself to others that much.
Much of SH readers tend to be silent, so if you want advice, come to forums to the "Story Feedback" section and ask for some. There are also pre-existing threads like
this one by kind-hearted authors who are willing to give your story a read and provide critiques and feedback.
