is ghosting ever okay?

I (18M) hooked up with a girl (19F) I met a few weeks ago from a summer school class. It was a very casual and no-strings-attached ONS in a motel room over a week ago, and I have no interest in remaining in touch. We are not friends otherwise, and the class has ended so we most likely won't run into each other again (neither of us attend that community college during the year). However, she recently reached out to me a couple times this week through WeChat (we had texted a few times last week to arrange the hookup but not afterwards), clearly seeming interested in meeting/hooking up again, which I thought had been clear would not happen from the fact that it seemed quite clear it was just a one night stand and we didn't keep in touch afterwards. I am not interested and was not prepared to hear from this girl after the first hookup, I didn't respond hoping she'd take the hint but she sent another message basically checking if I had seen the first one, and it came off rather clingy and desperate. I feel bad but I don't know if I should just wait for her to take the hint, as I don't feel like I owe her anything for a ONS which we left on polite and impersonal terms. Is it that cruel if I just ignore her and hope she gets the message? Is ghosting always a dick move, regardless of the relationship (like if there wasn't one to begin with)? Thanks for all your responses.
