If you mean to prevent them from ever coming back, that is not possible at the moment. Infinite blocks are possible, but sockpuppets are a thing for a reason. The best the VSTF or you (as a wiki admin) can do is revert, block, and ignore the vandalism and user, respectively. The vandaliser may eventually stop.

It's disheartening, but it may take a while.
