I am seeing these days that some of the Ideas in the Community Ideas space are not related to the Microsoft Tech Community but to Microsoft's some other products due to which status of those Ideas are changed to closed but they remain in the Community Ideas space forever without any reason.
To tackle this problem, I have a suggestion which is a moderation system which will work like this:
1. When an Idea will be added by a user, it will not be posted in the Community Ideas space directly and will go to the moderators of Microsoft Tech Community Lounge who will check whether the post is related to the Microsoft Tech Community or not and this system will also give a chance to check whether that Idea meets the Community's Code of Conduct or not.
2. If the Idea meets both of these criteria, then the moderator will allow the Idea to be posted in the Community Ideas space and if the Idea does not meet one or all of these criteria, then the moderator will not post that Idea and will send a private message to the user, the reason for not posting the Idea in the space and would also give a solution to that through the message.
