Is there such a thing as a GM glitch?

[Evie]

A friend of mine, and guildmaster, was threatened by another member who was upset that she reported him. He told her tonight that he, "Knew how to do the GM glitch" and that he would get into her guild, become GM and delete her guild.

For now she has reported him (again), stopped recruiting, and is making no new officers, but my question is, does this glitch exist? I had read about it happening once, but I thought it was accidental.

Can it be done on purpose?

Any info and suggestions would be appreciated. Thanks in advance.
