Mass Delete Inactive Users


Active member
I know there are some tools that enable you to do mass deletions on users for spam.
However, is there any way that I can do a mass deletion on users based on the last active date? I think it would generally be helpful with regard to permissions and cache rebuilds to eliminate users who are no longer on the board, however, I would like to make sure that their posts are not deleted and instead just set to guest or similar.
