Also, yes if the spirit box is used as evidence for a ghost in a speed run and the runners left the spirit box in the van... their run will be removed soon.

Alternatively, they can choose to remove it themself to help take the strain off of the verifiers to look through it if they know their run is now invalid.

Runs like that are still completely viable just by bringing the spirit box in as a third item and going for a specific ghost on a certain spawn.

It's bound to happen, and when it does you get WR. (or close to it)
