seems obvious this is the vandal returning and attempting to troll you, just block all the accounts. since you are a bureaucrat, i assume you are also an admin and thus have the ability to block them. If they continue to bother you after being told "to stop contacting", feel free to notify staff via  special:contact/general. staff will then leave the user a warning that may end in a global.
