Can Shift serve DNS blackhole responses?

If I want to block pages can Shift return a blackhole page?

DNS Blackholing in the malware prevention context (as opposed to the anti-spam context) is exactly what shift is doing when it is serving a block page for a malicious domain. Instead of resolving the real IP of the malicious hostname, we resolve a “fake IP” of our HTTP server serving the block EUN.
