They probably were just tired of having to replace the road signs that people were constantly stealing.

typical overzealous redditt mods

Sadly not a mile marker or they coulda done this- https://www.atlasobscura.com/places/41999-mile-marker

Members of the church had argued to the Ministry of Transportation of Ontario that it was inappropriate for their church to be located on the "Highway to Hell."

So go?

I knew someone who was in a band called 668, The Neighbor of the Beast.

I imagine the town itself has had some "Welcome to Redditt" signs disappear too.

In Poland we had a bus no 666 riding along the coast of Baltic sea to the city of Hel. It was quite an attraction to tourists to take a "bus to Hel" and people with at least a bit of sense of humour liked the diabolic touch to the line number. Sadly, after some backlash from religious people the operator was forced to change the number two years ago.
They chose to change it to 669.

nice

I would think that a town called "Redditt" would be equally problematic.
