Dinkleberg's GMod

In the past I've made ban requests using only the end-of-round scoreboard thingamajig as evidence for the ban (the somewhat detailed end-of-round logs, showing everyone's deaths and roles and who/what they were killed by; in this case the rdm'er in question got like 5 or 6 kills on fellow innocents, so not really any room for plausible deniability), but I was told that without damage logs specifically there wasn't enough evidence to ban. Why is that?

without the damage log we cant see if they were damaged first thus making it quite unfair to the possible rdmer

To extend on cryptic, i myself once killed 8 innos in a single round because they kept kosing me and i was just defending myself. So yeah its important to have as much undeniable evidence you can when making a ban request
