Developer usurpation
Developer usurpation is when a usurper with technical skills or technological access that the ordinary sysop doesn't have, over-rides the sysop power structure to put block IP measures or other restrictions in place that make it impossible for the sysop to undo what the developer does.
This is a power play of the most extreme kind, and strongly frowned upon even when it is done under the direct order of a GodKing. It makes it obvious that there is a power structure that is quite different from that which is "negotiated" in the "virtual community" - and in fact proves that there is no such community or community-managed space, but merely something like a corporate shopping mall, where presence is at the sufference of security guards.
