Thank you for your recent reporting of an troublesome editor to administrators intervention against vandalism. Unfortunatley, the vandal you have reported has not recently engaged in the act of vandalism. WP:AIV is for intervention against troublesome editors that are currently engaging vandalism and is not to be used to enforce punitive blocks against past vandalism. While there is no hard and fast rule, troublesome editors that have not made edits in the past 15 minutes, especially after being warned, are generally not blocked. If you have any questions regarding this, please let me know on my user talk page
