Certainly.  Use

group this-group-of-hosts-is-denied-and-logged {
	deny booting;

	host denied-27-f2 { hardware ethernet 00:11:22:33:44:27:f2; }
	host denied-c3-0f { hardware ethernet 00:11:22:33:44:c3:0f; }
}

group this-group-of-hosts-is-ignored-silently-without-logging {
	ignore booting;

	host denied-59-9b { hardware ethernet 00:11:22:33:44:59:9b; }
	host denied-a9-0b { hardware ethernet 00:11:22:33:44:a9:0b; }
}

We use this as one piece of our DMCA takedown strategy.

Note that the former can get quite chatty in the log files.
