A total of 3,820 complaints did not warrant investigation, the telly watchdog has decided.
They include 469 complaints over the result of the final, which saw Helen Wood triumph over Ashleigh Coyle.
Last month saw Channel 5 respond to the claims by releasing a statement denying numerous reports of a 'fix', insisting that Helen had won fair and square.
Ofcom also rejected other complaints that had accumulated over the series, including some 1,573 objections to perceived bullying and sexist comments from housemates Ash Harrison and Marlon Wallen.
Another specific incident which saw complaints was Helen and Danielle McMahon's row early in the series which resulted in over 200 complaints when Helen snapped: "Stop s**gging Jesus you f***ing tramp.” These were also not upheld by Ofcom.
However one episode has resulted in an investigation, namely the highlights show that had aired on August 7.
The Ofcom did reject 12 complaints about this show but has decided some of the other complaints do warrant further investigation into whether or not not Ofcom's Broadcasting Code has been breached.
22 complaints were made about spin-off shows Bit On The Side and Bit On The Psych, but these were all rejected "because they did not raise issues warranting investigation."
