Even The Sarah Jane Adventures, of all things, has a handful of minor edits on iPlayer. I know the first episode has been trimmed to remove a comment about a schoolgirl fancying an older man - and also a gag whereby an alien, disguised as a human male, shows disgust at the thought of entering the women's toilets. There's also a Series 5 episode which has a number of trims to remove factual inaccuracies relating to Native American culture... This episode was initially missing from iPlayer altogether, while the edits were being made - apparently a complaint somewhere over the years was upheld against the episode. So even CBBC isn't safe from being sanitised on streaming.

If anything, changing standards makes content for children more likely to be edited than anything else.
