I've done this every 2 years along with the 'Hottest Celeb' competitions for about 4 years now... in 2012 we crowned Chris Brown TiBB's most-hated celebrity, and back in 2010 Jedward won the dubious title.
All that needs to be said for the rules is:
- They have to currently be in the public eye; no TiBBers, people from your work or Big Brother housemates from 2005

- Come up with 5 celebs you hate and just post them in the thread. Please check this OP to see they haven't already been suggested though

(a quick way to do this is using CTRL+F to search for keywords like their name)
- Once we have about 100/120 I'll begin the voting.
Rounds
#1: Laganja Estranja, Justin Bieber, Gwyneth Paltrow, John Kerry, PSY, Nigel Farage, NeNe Leakes, Lady Gaga, Rio Ferdinand & Robin Thicke
