What for accounts are these? One might think lost wallet, but the owner proved that it's not.
It's almost impossible to determine if a wallet is lost. Lack of activity is not enough pointer that an account is lost, it is just dormant at that time.
I personally don understand the point of following or discussing activity on different addresses. It does not impact the Bitcoin space and it's purely natural to have an address that has not moved or received funds for a period of time.
