As this amounts to A record forgery, yes DNSSEC clients will prevent this. There is really no technical difference between this practice and the poisoning that DNSSEC is defined to defeat.
Of course there are plenty of other ways to blacklist or redirect IPs - using routes, RBL subscriptions in software firewalls or through browsers like the google safe browsing subscriptions. DNSSEC won't be the place to do it, though.
