I know in my experience, I've always tried to talk to those types of users on their terms and make them understand what they're doing and how they might better X Y or Z, depending on what the issue is. That rarely tends to work in the moment. But after talking it out with them once or twice, and others chiming in, then they tend to get it.
Unless they don't. Then they make like KT and escalate to a bannable offense and we're done either way

. The hardest part is putting into their own terms so they'll both understand and WANT to actually make a change. But I try to give everyone the benefit of the doubt. If then they do things progressively more doubtful, then they tend to bring punishment on themselves.
