Its like the people who used to ask "why can't we just S2K why do we have to /me" before there was any sort of script system that tracked who actually clicked first.
The one time I actually saw that happen was in an event in 2016 and the guy who actually fired first missed his first shot intentionally, got killed in response and tried to ban request that almost passed bc there were no damage logs from him so it looked like RDM from the victim.
It was only overturned because someone else nearby happened to be shadowplaying
