Their names and images were specifically suppressed at sentencing in the High Court at Auckland.
Breaching suppression carries a maximum penalty of six months in prison and/or a fine of up to $100,000.
The five people who the defendant allegedly harassed are all regular targets on the website named on court documents and have allegedly been the subject of his vitriol over a significant period of time.
His alleged actions occurred between December 2012 and July 2014.
The man could face up to two years in jail if found guilty.
It is understood he has pleaded not guilty to the charges and will be back before the court next month.
The issue of his name suppression will be revisited at that appearance.
The man could not be reached for comment today.
