The first one was insanely suspicious, you decided to dig one very specific block that had great loot (looks like a treasure chest) and you dug a even more suspicious hole to a ravine, which it took you a few seconds to do and was insanely suspicious because of how specific your digging was. The second one was suspicious it's obviously fake, if I were a moderator seeing a speedrunner do something so odd and specific I'd say it's suspicious enough to be rejected, you get great loot by doing something that isn't normal, I can't be 100% sure it's fake but I can easily tell it's insanely suspicious and looks fake.
