Do ninja tickets get investigated beyond looking at the screenshot?

[Massile]

Context:
HoR last boss, heal & tank item drop, hunter in group rolls need on both and tries to sell it to both heal & tank.


I make a ticket on said hunter, screenshotting the rolls & chatlog, but I forgot the fine-print in the rules that said screenshots need to be fullscreen & uncropped, so the GM response was to simply wave the ticket away under those grounds:

Now here's the thing; While the technicality of "We do not accept edited or cropped screenshots" is a thing on its own, it is different to saying "We do not look at edited or uncropped screenshots".

In that sense, here's what the GM saw (of course the name of the ninja being censored here now before I get slapped for "witchhunting" or the sorts):

Spoiler: Show

Again, while the technicality of "no cropped screenshots" has its time and place, if you read between that reply however, it highly implies that GMs commit no further investigations past looking at the initial provided screenshots.
In other words; what does this fullscreen picture provide that is case-sensitive, that isn't already included in the cropped version?

Spoiler: Show

Any person with at least the slightest amount of common sense would realize that the chatlog alone is rather damning in regards to if ninja-looting occured or not. Surely this would be reason enough to investigate a little and do a simple search in the SQL logs, or whatever other tools GMs have access to, as to what this hunter did with those 2 items? Why is a rule only coming into effect when someone reports on it, not when it was broken to begin with?
These are pretty large red flags that (valid) screenshots are the only thing being looked at in regards to ninja looting reports.

They need to see the whole context. People have tried making false reports from other servers in the past so the GMs use whatever information is in the screenshot(s) to verify that it actually happened here.

Tampered evidence. Doesn't matter what it shows, it's assumed fake and invalid - as it should be.

Create ticket with your unedited screens. What's your deal man.
