Another "Is this still available?" Response

Its been my experience that the main reason for those responses is people using cell phones. That "reply" button is right where you swipe. Ive done it to people a hundred times as I've had it happen to me often as well.
Doesn't necessarily mean its a scam. Probably just someone scrolling and accidentally hits that button.
If I'm genuinely interested in an item, I ask a real question. I have had it happen where people use the button for a legit reason too though.
And I think there is a button that lets you respond with the automated response, "yes it is. are you still interested?"
Just one guy's two cents. lol.
