As an admin on your Wiki, you are more than within your right to block that user as you feel justified. If you notice the user in question has other ill editing on other Wiki's you certainly may report it as Vandalism, or as Users needing checked globally. They will be more than happy to do a quick search about the user.

Otherwise... thanks for the warning!
