I know that if you delete your own question that was downvoted, after some short time the reputation gets recalculated and you get your lost reputation back.
There are some other discussions here that ask about this:
Initially I asked if you do you get the ability to automatically delete your own non-answered question just above some rep threshold or even if you have 1 rep you can do it? The answer is yes you can, regardless of your reputation ( How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion? - thank you, Mat)
So as a sole question, do you think the system is correct / fair or is there any principle that is based on? I mean, someone in the above questions said that if you do it too much, you get banned. But even if you do it once a month, it's sort of a trial and error system. I figured if you don't get your rep back after deleting a poor question, then you'll be very careful next time when asking a question. And I'm not talking about one-time users, I'm talking about users who want to build a solid rep and be respected by the community.
And I'm clearly not saying that the current system is incorrect / unfair. It's very good, but I just want to have some opinions regarding it.
