Thing is just about anyone can say someone using Pkhex or powersave, but chances are likely the 6 IV Ditto was edited since there's no way to RNG abuse legit one. Either way if you are using a 6 IV ditto yourself, it shouldn't be much of an issue as there's no way for GF/TCPi to check without looking at identical PIDs for clones (note: they don't do). Just not we don't blame anyone for using Hacks here since at the end of the day, the Pokemon with perfect Iv stats all across is an expected result to have in comp.
The hack checks are usually only to check for irregularities like 252 evs in all stats, a low level evolution that's not possible, event mons with illegal egg moves, or others stuff. Not so sure if memory exists in this gen like in ORAS, but that's usually one way to determine hacks, though not the best.
If you are going to use Pokemon for VGC events, at least make sure they are 100% sure they aren't blatant hacks as those examples I'd mention.
