Alrighty, I think I've pulled together all of the suggestions; apologies if I've missed or mis-stated something. The following text would be inserted into the CoC
If a violation of these guidelines occurs:
It is the responsibility of the relevant forum’s dedicated moderator to provide a mod-voice warning (in the relevant thread and via PM to the offender) which specifies the violation. If the warning is ignored, it is to be followed by a 24-hour suspension of posting privilege for the person who is violating the CoC (PVCC for short). If the PVCC is the dedicated moderator of a forum, it is incumbent on any moderator to take these steps. Three suspensions will result in the outright banning of the PVCC.
If the PVCC is a moderator, mod privileges will be removed at the time of suspension. They will not be reinstated until the individual involved has unequivocally and publically shown that they understand why their behaviour violated the CoC. Moderating privileges will not be reinstated until the community has had an opportunity to provide feedback to the Moderator quorum (either through a discussion thread and/or vote) with regard to returning privileges.
If the PVCC returns from suspension and refuses to either engage with open discussion of the violation or indicate that they require time out from the issue (i.e. to let defensiveness fade, etc), then the moderators (excluding the PVCC mod, if that is the case) will confer to determine whether a longer suspension or outright ban is required to manage the situation.
24 hour suspensions may be implemented by a single moderator. Longer suspensions must be approved by at least two moderators; bannings (excepting those which fall under the 3-strike policy) require the agreement of three moderators. If an egregious violation requiring an immediate banning occurs, and three moderators are not available to deal with it in a reasonable timeframe, one moderator may implement an indefinite suspension, pending the availability of other moderators.
One thing I think we should be covering specifically here is what exactly constitutes 'ignoring' a warning. Obviously continuing with behaviour that's been specified as a violation is ignoring it, but should we require the PVCC to post acknowledging & accepting the warning? I don't think it's congruent with maintaining safety in the forum space if the PVCC can, for example, simply opt out of the discussion after a violation.
