[Macie Lightfoot]

For the record, Charley's whole MO is that she's incredibly righteous almost all the time, but happens to express herself in the worst way possible <3 what a gr8 combination. And Marcus is creepy and gross and not funny at all so w/e

Now to answer the topic question at hand, I'll think of people who have legitimate fanbases:

BB1: Craig (self-righteous, hypocritical, boring)
BB2: Brian (The Only Gay In The Village isn't cute)
BB3: Kate (BORING), Alison (annoying, posterchild of weakbitch.org)
BB4: Ray (lame and annoying and not one of the hidden gems of BB4)
BB7: Grace (her arc can be summarized as thus: she was a bitch who got bounced early and then threw water on someone. Next.)
BB8: Samanda (BORING), Liam (cliquey and smug and self-satisfied and not hot at all. In fact, he's doughy)
BB9: Rex (tryhard), Darnell (awful), Mohamed (gross)
BB10: Siavash (soooooooo awful), Marcus (lame af), Freddie (annoying and cringe), Karly (blonde w/ a thick Scottish accent and that is it)
BB12: Aaron (not even getting into it), Faye (kind of lame aside from Jem-related moments), Harry (lame tryhard)
BB13: Caroline (pathetic), Arron (I don't think he rly has any fans anymore but he's gross), Chris (his small fanbase never made any sense lmfao)
BB14: Dexter (gross and BORING), Hazel (was rly bad at being Hazel), Dan (annoying and not The Big Character people acted like he was at the time)
BB15: Helen (not even getting into it), Ash (why on earth are there Ash apologists), Toya (she sucks)
