I’ve seen this happen a bunch of time now that people just ask a question and it’s deleted a day or so later. Do they delete the question themselves, or is that some automatic thing? If they do it themselves, why?
*edit*
Thanks for the great answers so far. Very insightful. Please keep them coming, I’m curious to more points of view.
Or they do get the answer they want and now they don’t need to get anymore answers.
I’d then update the post thanking every one for the answers provided, and that you don’t need any more.
For them spaces on the internet are just a question and answer machine - why would they thank us NPCs?
Fair assessment. Thank you, fellow NPC :)
