Generally, one-off incidents of vandalism aren't acted upon by local admins. They need to see multiple instances before they consider taking action.

If the user continues to vandalise your talk page on a specific wiki, you can ask that wiki's local admins to block the user from editing at that wiki.

If the user vandalises you talk page on a number of different wikis, feel free to talk with the VSTF. They deal with cross-wiki spam and vandalism, and have additional powers that can help prevent it from happening again.

Generally, in both of these cases, admins/VSTF will warn the user in question first to stop what they are doing, so don't expect immediate blockings. If the user continues, admins/VSTF will take the relevant steps, per local wiki policy and/or VSTF policy.
