He registered an account yesterday, posted this 3 minutes after his account was registered and since that time, he posted nothing till now after questions as been asked from him or her to explain better about what he posted, but he is not reading what people are posting. Maybe he or she has seen good answer to his question already, but it would have been better for him to read what people also posted on this forum.
Even if they have seen a better answer to their question, they should come and acknowledge it but since you said it's something they did three times repeatedly, my best guess is they just want to spam.
If you're curious about something, you make sure to follow up whether it has been attended to. Let it not be that tomorrow they'd open a thread asking why this place is harsh to newbies or why they can't get merits
