It depends on the situation. Im strongly against griefing an entire server. My favourite server got griefed a long time ago, because another server thought we "stole" the entire idea, though there are THOUSANDS of servers that are the exact same type. But I still don't exactly support griefing. Sure, griefing a griefer can let off some steam, just griefing someone who did nothing at all isn't right. Griefing just for the lols can be funny at times, videos of griefing a 10 year old are often very funny. I generally don't support griefing.As you mentioned in your original post, taking down a server ran by an annoying 9 year old can be a good thing. A server funded by his mom's credit card, paying for a faction & a diamond sword isn't a good thing, so griefing it might bring at least some benfit. By the way, you get paid to grief servers? Your job is to grief servers? Seems like a pretty fun job to me
