>>102784228I would agree with that notion. I feel that purity is measured using the vtuber themselves rather than their roommates.
However, there is an argument that says the roommate's actions should be taken into account as to do otherwise is like treating the roommate as replaceable. That clearly is incongruent with reality if you remember the Gamers situation (roommates were replaced by new people and the agency died as fans were upset).
It is a tricky predicament to solve...
