I thought Jollygood was giving negative tag to those 5 members, but when I checked it turns all of them was got neutral tag, so where's the abuse of trust is?
It's completely fine to leave a message with neutral tag, if other users are disagree with Jollygood personal message, they can vouch the user didn't a low quality poster or asking Jollygood to recheck their posts.
If it's negative tag I will it's abuse of trust, but the truth isn't.
So tagging someone's account with neutral seems like a good compliment to you right? It's a defamation of account and that's a bad reputation to the affected users. No one will care if they really produce low quality posts as he claimed.
