I once got a zap on a week old post. I felt known. It was also a really big zap, but even if it had been a normal one, it didn't come across as creepy to me. I had already interacted with that person though, but I don't think it would have mattered.

I've heard others talk about feeling weird about it, but usually it was on someone's profile that they liked romantically, but hadn't really talked to yet.

If it's not romantic, I don't really see the creep factor. It's more of an encouragement because someone liked something I wrote.

But having written books might help with my perspective because I want people to read my first book even after I've written 5 more. (I'm working on book 3 now)
