This is in the Mod Rules for this section of the forum, copied and pasted, word for word, with important bits in bold:
GM Autonomy – in most matters pertaining to the thread, the GM has the final say, as it is their plot and we do not wish to interfere with running RP's. Who is in, who is out, calls regarding the storyline and the rules by which RP's run (including how many paragraphs, post rate and order, etc, etc...) who needs to leave and so forth. The only time the moderators tend to step in is when the rules listed above are being violated, otherwise the GM is left to sort it out and deal with their problem players. Of course, the GM can also call us in, but that's usually when someone refuses to leave an RP alone after being asked to leave. Eventually the GM's will have the power to even more closely moderate their thread, but in the meantime, the mods will enforce that power if push comes to shove. If asked to leave by the GM, it's advised you just leave with a little dignity.
