I've gone through each series (apart from BB1 and 2) because I can't remember them, and taken who people think were the most boring that series. All you have to vote for is the person who you think is the most boring out of all of them.
I genuinely couldn't think of anyone boring in BB3 and BB5.
Edit- Roberto is BB6 btw, I just forgot to add that on
Oh and feel free to add any suggestions if you don't agree with my list, I don't even agree myself, I missed off Anthony from BB6
