People always say BB don't care about vote, but in this season whenever they done the voting through public, it turn out to be real. As per spoilers Rahul evicted over jasmine is also 100% correct as Rubina & jasmine are the most popular faces of this season, they have dedicated fanbase from their previous shows. So even if jasmine lost many fans than earning in BB, but she has fan power of her pre built fanbase.
While Rahul is all about PR. PR help to create buzz but they don't spend money like fans of Rubina & jasmine. And most of public tend to have herd mentality, so they get influenced through such buzz. Hence Rahul got eliminated fairly by BB based on votes.
1. In first week when shehzad, Abhinav & jaan were in bottom 3 and jaan got the least votes, they manipulated the situation but never claimed shehzad got out due to votes.
2. Then when Kavita, Nishant, Rubina & jasmine was nominated. They evicted Nishant through housemates vote and didn't hide the fact that Kavita despite being senior popular face actually got less votes then junior Nishant.
3. When abhinav, Ali & puvitra nominated last week along with other contestants & pavi due to lack of votes got evicted.
Few khabri's posted that puvitra got the least amount of vote, which turn out to be true but those trends are 100% fake and they do it to increase their followers by echoing their voice, but in reality voting details are highly confidential. So people should not take seriously these khabri's who has no intention other than getting more followers for their account.
This season BB was 100% real with voting whenever they opted for. So crying foul over Rahul's eviction is unnecessary.
