A viewer's complaint against children's presenters Dick and Dom was among 31 which prompted the BBC to take further action during the last part of 2004.
Dick and Dom fell foul of the BBC Complaints Unit
Their near naked appearance to promote their show on the CBBC channel led to the complaint in August.
The station's management told them that acceptable limits had been exceeded.
An inappropriate reference on Trinny and Susannah's What Not To Wear show before the watershed also led to a grievance being upheld.
An editing error led to the word being left in the programme, but the reference was removed before transmission elsewhere.
During October to December in 2004, 13% of the total of complaints dealt with by the BBC were upheld, resulting in further action within the corporation.
Entertainment and factual programmes were the source of a majority of the complaints, followed by news and current affairs programmes.
Chat show host and Radio 2 presenter Jonathan Ross was reprimanded for expressing views on one side of the fox hunting debate.
Jonathan Ross was reprimanded on two occasions
Following a letter of dissatisfaction from a listener, Ross's co-presenter Andy Davies was asked to reacquaint himself with the BBC's producer guidelines, which give reference to matters of impartiality among BBC broadcasters.
Ross was also the subject of another upheld complaint in September 2004, when an explicit reference was made on his programme when children could have been listening.
Other examples of complaints which warranted further action was the use of the word "pikey" in BBC Radio 4 programme The 99p Challenge, which two listeners found offensive.
The show's producers were reminded of the word's long-standing meaning, although adjudicators conceded that it also had a modern connotation.
Complaints dealt with at the BBC are usually settled within 20 working days, but in the last quarter, 7% of them required a longer and more complex investigation.
