We should be careful in defining the "inactive" state here. For example, I use an alternate account to run mine, and rarely do anything else besides signing blocks. Just because it's socially inactive in my case does not reflect the case you are describing.

Maybe something that would be more reasonable would be if it's not signing blocks for more than 30 days, and is an enabled witness. That, in my view, should have more visibility, yes, so that people can make a call about what to do.

Sorry if I missunderstood what you meant by activity.
