You don’t have to ghost someone. You can kindly say you aren’t ready to date and you apologize. And it’s much more unkind to just put someone off until they stop asking. It’s child’s games.
It’s also no fair to be on a dating site when you aren’t dating. People aren’t there for your amusement and void filling. That is what’s most unkind.
