I'm a little surprised that the Internet Protocol Police have only just been formed. honestly thought they already existed 🤷‍♂️

@hacks4pancakes train seemed a little busier than normal this morning. I’m not a regular commuter but I use the train often enough to get a sense that this seems popular.
