Having been dubbed the "demolitions expert" of a former team, I can admit that 12-year old me found griefing both fun and hilarious. However, after a dispute between a personal friend and my build team which ended in him setting fire to everything we'd built- we liked working in wood- I found exactly how annoying griefing is for those who have dedicated their time and passion into a structure, only to have it destroyed by the "kid who kicks over sand castles" so to quote Sump.
That being said, I was unaware that professional griefing was a title, let alone a position viable for payment (That's nothing against you Nicole I just happen to live under a big blocky rock). I guess in Nicole's case it comes down to who is paying you for what. Do you get tasked to clean up servers that no one visits, or do people pay you to spite another person's server? I severely hope it's the former and not the latter.
Overall, I would say that I don't have enough experience on this subject to judge it formally, but my opinion still stays the same:
Any damage done to servers in attempts to spite or put down other people is morally wrong, title or no titles. Everyone has a moral responsibility to show kindness to other people, and that extends to respecting their belongings as well, even if the belongings in question are 9-year old servers with factions.
