My team was debriefing from their most recent bout and asked me what is the best way to get the officials attention regarding what should have been blatant game interference matter. The situation was white team lined up 4 blockers and a jammer for the upcoming jam. Nobody except black team realized white team had a blocker in the penalty box (obviously a pretty catastrophic failure of officiating for it to go unnoticed by the skating officials, penalty box manager, lineup tracker, and penalty wrangler). Shouting and waving didn't get any of the officials attention. So black team was wondering what else they could or should have done to get the officials to stop the jam before any significant advantage was gained by white team and for the interference penalty to be assessed on white team. They wondered should the skaters have all taken a knee to start the jam? Should they have run up to officials interrupting the jam to get them to notice? I didn't know what to tell them so thought I would bring it up here what you would want done.

I have had the scenario clarified:
as per 4.4.2
there shall not be two jammers in the penalty box!

Nashville Roller Derby are hosting their annual Scrimmage-a-thon on July 11th, 2020*. This will be held at The Fairgrounds Nashville in Nashville, TN.

We are seeking officials to staff the 6 scrimmages (each 45 minutes long) and be considered for two games after the scrimmages are over. Lunch and dinner will be provided for officials, with accommodations made for dietary concerns (we won't leave you high and dry if you are vegan, gluten free, etc).

This event is one that has been very successful in getting newer officials lots of feedback. We generally have several high level referees (several with Playoffs and Champs experience) there doing lots of watching and shadowing to give feedback.
This year we are again seeking to increase the number of high level NSOs available for feedback. If you think you may be able to give feedback, please consider coming.

There is no specific application close date, but we will be doing rolling invitations (hopefully every week or so, depending on the number of applications). So you should be able to make plans fairly quickly after you apply.

Apply here

_{* Yes, the date is correct. This event will be held much later in the year than usual.}

I get into that "argument" around here also.  It boils down to "what is the impact that you are penalizing?"

If you are penalizing someone for forcing an opponent out of bounds, or down, during a no pack: that is a loss of position -> Out of play block (no gerunds here). 

If the impact you are penalizing is that the pack did not reform quickly enough and this player was not acting to reform the pack -> failure to reform.

Some people try to say that "the blocker was impeding the jammer, so it is a contact penalty" to make the case for out of play block.  Impeding is only a penalizable metric for illegal blocking zone penalties (forearms, leg blocks, head blocks). 

Sorry, i fixed link.
