Dear
Reference
Thank you for taking the time to contact us.
I was sorry to read you were disappointed with the BBC News website. I understand you were unhappy that a headline regarding Gary Glitter referred to 'child porn'. I appreciate you feel use of this term is irresponsible and should be labelled ‘images of child abuse’.
To address your concern; the terms child pornography or child porn used on their own do not necessarily convey the reality of such material, so we should try to use other language such as 'images that show child sex abuse' or 'indecent images of children' to make this clear. Where possible we should avoid the term 'child porn', though at times it may be the best way to convey meaning in a short headline. In any case, if either term is used in headlines or summaries, the text should spell out the nature of such material.
While use of the term hasn’t been banned completely; the headline in this particular case has been altered to read: “Gary Glitter breaks down in tears over child abuse images”.
Rest assured, we do value your feedback. All complaints are sent to senior management and in this case, the BBC News team every morning and I included your points in this overnight report. These reports are among the most widely read sources of feedback in the BBC and ensures that your concerns have been seen by the right people quickly. This helps inform their decisions about current and future programmes.
Once again, many thanks for contacting us.
Kind regards
