I hate this way of “cheating”

I’m not sure if this technically counts as “cheating” but I just left a lobby where the host and another player were sisters, who I guess were sitting next to each other. In of the first games, I got imposter, killed the host, and then the sister said I killed her sister, I managed to get a tie by the vote and then kill the sister, but I later got voted out probably because of her. So then many rounds later I got imposter again but this time there were two instead of one, and I got paired with “chicken”, and also this time I was shapeshifter instead of phantom, so I shapeshifter as one sister and killed the other in front of multiple people which got her voted out and then me and chicken won. Then later not only did I get imposter AGAIN, I also got paired with chicken AGAIN, but this round the hosts sister left, but I still killed host immediately, and then me and chicken won AGAIN. Still very unfair way of playing.
