You can email the mods and ask them to do so. Footer contact link and mention “FP #x” somewhere in the subject.

What’s "FP" for?

False Positive of course. Why type of a full word with no ambiguity when you can confuse everyone with some obscure abbreviation ?

Functional Programming

Floating point?

Furry Platform

front page?

Maybe, but it seems odd that someone would refer to a submission by a numeric ranking that changes constantly.

If you wish to refer to the submission uniquely in the subject, as of a few years ago anyways they requested appending ` (1235676423)` to the end of it with the ?id=1235676423 of the comment/post/whatever that you're writing about. I tend to do so more in emails sent from a keyboard than from a mobile phone for UI reasons.

Hey I’ve seen people use email addresses as unique, immutable identifiers so who knows what crazy thing people will do.

Okay, I guess. Half of that is a far more understandable mistake, and the other half makes things easier for everyone.
