Okay, from here

BIG BROTHER 2018: WHO DO YOU WANT TO WIN?

Cian Carrigan 47.36% (952 votes)
Cameron Cole 24.18% (486 votes)
Akeem Griffiths 19.8% (398 votes)
Zoe Jones 8.66% (174 votes)

Total Votes: 2,010

We're now here

Cian Carrigan 45.94% (1,704 votes)
Cameron Cole 21.84% (810 votes)
Akeem Griffiths 17.01% (631 votes)
Zoe Jones 15.21% (564 votes)

Total Votes: 3,709

That would mean

Cian +752
Cameron +324
Akeem +233
Zoe +390


So it appears to me there is someone multivoting Cian and after a while this person starts to multivote Zoe. Zoe, as you can see, has almost doubled the percentage she was on. Cian is supposedly getting twice as many votes as Akeem and Cameron.

The TIBB poll by contrast has not changed much.

This was earlier

BB 19 2018 - Who do you want to WIN? [Final Four]

Cameron 36.17 % (102)
Akeem 26.60 % (75)
Cian 26.24 % (74)
Zoe 10.99 % (31)

Total votes: 282

Now it's

BB 19 2018 - Who do you want to WIN? [Final Four]

Cameron 35.38 % (173)
Cian 26.99 % (132)
Akeem 26.38 % (129)
Zoe 11.25 % (55)

Total votes: 489

Cameron +71
Cian +58
Akeem +54
Zoe +24

Whilst Tellymix had the bottom 2 right on Friday, I believe there was just 1.5% between the bottom 3. TIBB underestimate Zoe's popularity but Tellymix, after the rigging, clearly overestimated it. Before the rigging it was extremely close between Brooke/Zoe/Sian.

Cian's vote is more difficult. Clearly there is a genuine upsurge in support for him, but I do believe this is being combined with an obsessive fan multivoting to the top of polls such as Tellymix and BB Spy. The same person seems to be determined to boost Zoe's vote up as well, hence her sudden surge on Tellymix and the fact she's #2 on the BB Spy poll.

I still think the poll here is probably the most accurate at this point.
