Chapter3 seems to be cross-posting their training events into many groups, including those far removed geographically form where the training is happening.
My take is that this is crossing the line into abuse. Such events obviously are reasonably for geographically close groups, and also for http://groups.drupal.org/curriculum-and-training which specifically invites them.
I propose unpublishing/deleting these otherwise, but want to be cleat about our policy.
