With a show like Big Brother, which rewards contestants who lie, manipulate, and backstab each other, it's no wonder why there have been so many villains on the show for the past 20 years. Although there are entertaining antagonists who are mostly loved by viewers, like season two's Will Kirby, there are many more who played the game too craftily, and became hated by fans.
Since the series is now in its 20th season, we decided to take a little stroll down memory lane and revisit the most infamous houseguests in Big Brother history. Although many controversial contestants have disappeared off the face of the Earth (especially the ones from the earlier seasons), we were able to find a handful of houseguests who've changed for the better since the show.
Below, see what they've all been up to.
