Is it possible to disable personal messages for a specific user?

It sure is, but only very recently. Check out the release notes for details:

Limit who can send you PMs

Prefer to only receive PMs from a select few users? You can now specify which users can send you PMs via the Only allow specific users to send me personal messages user preference on the Users page. Only users on the list (admins and moderators can always send users PMs) will be able to send PMs to you.

If you prefer not to receive any PMs (staff exempted), disable the Allow other users to send me personal messages user preference on the Notifications page.
