Not universal but it's the unfortunate reality that people obsess over stuff they don't like as a form of internalized repression. They better be careful though, looking at so many furry images while downvoting they may eventually catch the pathOwOgen.
It's nice that you can get this information by querying the database directly but it would be nicer still if it was built into the admin or mod interface somehow. Although I imagine in order to compile that information you used some sort of DB aggregation which could be unexpectedly resource intensive on larger instances so perhaps not.
I wonder how possible it would be to create some sort of plugin system for lemmy to add functionality like this and more that would only be of interest to particular lemmy instances. That could help to keep the core of the server small and lightweight while giving people the option developing and installing server resident bots, additional functionality, and user interface enhancements as they see fit.
