I got so exasperated about this in a breed I once had, that I wrote to both the dog papers and the KC about it. (Named breed in the dog papers, named people to the KC)
It did stop after that :-)
Following the letters it was rumoured that the Breed Club wanted to expel me for bringing the breed into disrepute, bring it on said I I'd love to talk about it openly at a SGM etc, strangely they dropped that idea (some of people concerened were on Committee and others friends of some committee members)
In my letter to the KC I asked why Champ Show secretary's didn't collect empty envelopes to compare against alleged losses in post, especially with repeat offenders.
A number of people approached me after going to press as it does happen in other breeds.
Interestingly with on line etries it should occur less now.
I apologise to anyone who has legitimately had an entry go missing, I am solely talking about repeat offenders, in the breed concerned I think it had happened at something like 7 shows!!! And is just downright cheating imo
So my suggest, make a fuss lol
