As I see it, the purpose of this rule is not to avoid the falsification of evidence.
I would think it'd be fair to define the minimum for evidence as:
A (set of) screenshots can be accepted as evidence if they unfailingly present a clear narrative. That is to say, a clear narrative requires that: the context of events can be determined from the information present, and if there are multiple screenshots the sequence of events can be determined or at least easily inferred by comparison of the screenshots.
Cropped screenshots cannot present a clear narrative in all but a couple of extremely egregious cases.

Is taken to mean that your case may be handled regardless of the quality and nature of your report, or even possibly regardless of whether or not you report at all. An incomplete report is unactionable in and of itself, but it may not actually be incomplete when compared with information we already have. If we discover as such, and it forms a complete case, we
may at our discretion decide to take action based on that completed case. In short, there are some cases in which your report could be "so and so is an idiot", and we may be able to collect enough evidence ourselves to do so without additional input and we may then decide to act on such evidence. In short, your report being shit does not mean that we definitely won't ban the person anyways.
However, if your report is shit, we may also completely ignore it. That's really what the line is getting at.
Having cropped images means, in the vast majority of cases, that your report will not actually have enough context. It is not the place of the user to decide what information is unimportant enough that it can be discarded entirely. If you decide to discard some information and it turns out to be important to us, we may not be able to act on your report. You are not expected to know what information is important as such, except insomuch as that it is almost always some subset of "all of the information on the Toribash screen". I would generally not require that your screenshots include your desktop, or anything not Toribash-related.
Asking people not to submit cropped screenshots requires people to avoid accidentally leaving out information that may be critical. In some cases it may not seem like this information is critical, if for example you're just taking a screenshot of somebody spamming something offensive in a server. However, it is still good practice to include the entire Toribash window in that case: there have occasionally been instances where people could potentially be impersonated by other users through certain clever tricks. There are ways to identify these tricks, but if you crop only to the offending lines, there is no longer enough information to even examine the problem.
Furthermore, allegorical evidence from other team members suggests that this rule also decreases the rate at which reports are egregiously falsified, which is generally a good thing.
For the minor inconvenience that this rule poses, it seems reasonable to request that screenshots not be cropped.
As a catchall, however, if your evidence is insufficient in any way, your report might not be handled. As a further catchall, if your evidence is insufficient but the user you're reporting is utterly horrible, we might ban them anyways.
Since uploading cropped screenshots is unacceptable, we might give you a warning or infraction for doing so, or we might ignore your report. In some cases, we might not do any of these things.
If you upload uncropped screenshots, your report will generally be taken seriously, unless those screenshots turn out to be falsified in some other manner. By taking your part seriously, it becomes easier to handle the situation in a timely and reasonable fashion.
