I am really enjoying that there are so many users already with the close-vote casting privilege and actively using the review queue tools to help maintaining this site.
However, while going through flags I often notice, some questions are closed with the following reason:
This question does not appear to be about Ethereum, the decentralized application platform and smart contract enabled blockchain, within the scope defined in the help center.
This is not certainly true for some questions like this one and I notice this happens quite often in relation with mining. In my eyes mining is an essential part of Ethereum and clearly on-topic.
If the question is of low quality, vote down and add a comment to help new users on-boarding by explaining how the question could be improved. If the question is hardly salvageable, use the unclear what you are asking reason. (And so on.)
But please don't close questions as off-topic which clearly relate to Ethereum. Discuss below if you disagree. Thanks :)
Edit: Another one.
