Thought i'd add cheeky reasons too...
BBCAN1
Fav Male: Alec was such a fan of the game and I loved his calculated personality. The housemate most similar to me mentally speaking.
Fave Female: Topaz was a huge fan and it showed in her gameplay! She was beautiful inside and out and slay a bit for sleeping all series and making final 6

Least Fav Male: Peter was rude, obnoxious and everything wrong with a superfan.
Least Fav Female: Danielle was dumb, played the game terribly and had an annoying voice,
BBCAN2:
Fav Male: Kenny was everything i've always wanted in a Big Brother houseguest. Finally a gay guy cast who is similar to me in personality.
Fave Female: Neda because she's the best player to ever play BBCAN and represents superfans so well.
Least Fav Male: Paul was so annoying and had no game.
Least Fav Female: Sarah because all she did was cry and have a very plain personality.
BBCAN3:
Fav Male: Jordan for him talking on the feeds for hours on end about past seasons of Big Brother. Made the best viewings ever.
Fav Female: Naeha for her pure and passionate love for the game and the show. Also for being the fiercest girl in BBCAN history.
Least Fav Male: Johnny because he was obsessed with getting the straight guys to like him. Like dude, give it a rest it's so weird...
Least Fav Female: Brittnee for being everything wrong with a recruit. Awful gameplay, a jealous person, a model, full of herself and for being obnoxiously adored on the forum. And for getting rid of Kevin and Willow, two far more deserving players than herself. Gross.
