The forum hivemind has realised (or at least re-realised) that, pretty unsurprisingly, it's easy to fake a 3x3 solve. Therefore everyone else has decided that (out of jealousy, cynicism, whatever else idk) people aren't allowed to lay claim to a lucky average without being shot down as 'fake'.
Afaik, Kim's never tried to pull anything like this in the past - why shouldn't we trust him? I mean, if someone has a history of fake solves then I could understand, but why him? Because the possible actions of other cubers recently have cast a bad light over the community? It all seems ridiculous to me...
By the way, awesome average Kim. At this rate it won't be too long before you can get this average on a non-ridiculous set of scrambles.
