I agree that high amount of Low Quality posts are preventing to use much time for each review tasks, and thus produces a deleting habit.
But what is the point of closing/deleting posts, which has even received a bounty?
Ie. this answer of me received even a Bounty; Where does gravity get its energy from? ...but it was still deleted!
This Answer received also the Bounty; How can a bowling ball curve in both directions? ... it's also down voted and is proposed to be deleted, at the Comments is said;
This does not provide an answer to the question.
Though the person who asked, even provided me a Bounty for my answer!
I think the main problem is that some actively moderating persons are just down voting and closing questions in "Facebook-style"; 5 sec preview and Thumb up/down. I noticed this behaviour clearly in this deleted question; Mysterious temperatures of Mimas? where every one can see through it's comments how difficult it might sometime's be. The Question might got closed just because it used the word "mysterious" in it's title, though this was a direct phrasing used in the original source of the explaining picture.
Text from question;
But why conductivity should vary so dramatically across the surface of Mimas is a mystery.
Comment 3 from me;
@CuriousOne "But why conductivity should vary so dramatically across the surface of Mimas is a mystery."
Comment 5 from me;
@CuriousOne "What is the physical explanation for dramatical conductivity variations across the surface of Mimas?"
Then suddenly, when the word "Mystery" is away;
Why didn't you make THAT your question in the first place... – CuriousOne
It should be noted that this "CuriousOne" haven't ever asked a single question by himself. With this I don't want to attack against the persons of moderation, but it seems that there should be some mechanism to prevent this "Facebook-like" dalmatian-species-specific-moderation-style to reproduce.
This is part of the problematic I have talked before; Can we stop closing questions as "unclear what you are asking" for OPs above certain reputation?
These "Unclears" are also about to be Deleted;
Why In Thermosphere is He and O divided as measured?
How is it possible that Thermosphere can maintain so much heat?
Numerical model for a Air core Vortex, why it's still so limited?
1. Should it be prevented to close/delete posts which has received a bounty?
Should it be more limited for a single person to give "unclear-close-votes".
Should it be more limited for a single person mark questions as a "Low quality posts".
