[nznog] use of open proxies and the Crimes Act

Suppose a Bad Person (living in NZ) were to use an open proxy (located in NZ) belonging to a Silly Person (also living in NZ) to do Bad Things (eg leeching international bandwidth, posting nastygrams, etc). Am I right in thinking this would fall under recent amendments to the Crimes Act? If so, I might be making a few calls tomorrow. Stephen
