The Internet is a bad neighbourhood.

Having a long-term internet-facing server is a bit like having a car which you have to park somewhere dodgy. At any given moment you can check in on it to find a dozen furtive individuals trying to pry the hubcaps off, graffiti over the windows, stick bananas in the tailpipe and, of course, break into it and drive it away.

This is not great for one’s peace of mind.
