Goes on all the time, everywhere.
I used to be involved for over 20 plus years in competitive dog training for sport, police, and military dogs. I turned away from the organizations (not the dogs) for reasons of cheating, and dirty politics.
A common saying involved with competition= " It's only called cheating, if you get caught" unfortunately...
Hope the cheaters see justice. How they can feel good about what they do blows my mind.
Just my 2 bits.
