Stashes dug up by foundations don't send a warning

A couple of months ago facepunch changed it so that stashes are automatically dug up when a foundation is placed over them. I figured it was only a matter of time before cheaters started using foundations to avoid detection and I witnessed it for the first time today.

Would it be possible to add a warning when a stash is dug up by a foundation?

I've been noticing cheaters doing this as well which makes entirely defeats this plugin, would be really fantastic if this were to be added!
