The current models are trained with data from 2016. We should run a new labeling campaign so we can boost the number of observations and the recency of the information.
@putnik helped us run the campaign in the past. I wonder if he'd be willing to help us gather a group of people to label edits again.
This task is done when a new labeling campaign is created for ruwiki with a recent sample and someone at ruwiki is notified about it so they can announce it.
