The significant change in personality a forum poster gets shortly after he/she realizes the kind of authority they have after being ranked to a moderator status, enabling that individual to be aggressive and assertive instead of passive like they usually were before they had power.

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.
