unless you keep spamming it to make up a significant amount of logs for the site, i doubt anyone would notice...

It might be useful to include a link so people from here can spam it. Like this: http://www.craigkerstiens.com/2019/03/29/okrs-arent-going-to...

Are there people who do this?

I look at 404s (and other errors) in prod. Helps find front end bugs and any malicious requests. A 404 should be exceedingly rare in a mature application (depending on the application of course and users' ability to create AND delete data) so it's often a useful metric for figuring out if something's wrong. I don't usually tail the logs and use monitoring instead, but same effect. After a certain scale, I imagine this becomes harder to do and requires different tooling.

Admittedly I'm grumpy today. I sometimes do this "404 trolling" to yell at people.

the knowledge of this has made me happy. :)

Thanks.
