May be mod can do something about it. Leaving unhandled will discourage the reporter not to repeat the same. Thoughts?
If mods are not too busy perhaps it's not a big deal to handle those old reports although I do remember hilarious mentioning a few times that a flood of low-value post reports interferes with the handling of more urgent ones.
Tons of accounts were just banned recently for plagiarism found in very old posts so their is definitely precedent.

It seems to me that the general community considers this sort of post digging to be fair game so keep that in mind..
I would consider reporting old plagiarism fair game (or malware etc but those are typically handled contemporaneously). Old shitposts is kinda a waste of time for everyone involved.
