homedns.org is part of the free (and paid) dynamic dns provider
dyndns.com. Services like that terminate accounts very easily when
they get a sufficent number spam report. Of course this doesn't
prevent the spammer from spamming using other means, but can at least
disturb him.
Forward your complains here. Be sure to include URLs or proofs of the abuses.
