Right - again from a 'lets address a problem we can solve' department,
its very very difficult for an implementor to really identify which image is nude and which is not. One way this can be done is if the image owner provides enough keywords to the image like 'naked' 'nude' etc. so that it can be idenfied. However, as you know, there are many images that dont contain such identifiers.
(As an example, take images.google.com -> it has an option of safe search, but even when that is enabled, it does produce several nude pictures).
So, instead of trying to filter nudes, if this feature at all is worth providing, maybe once can consider simply giving each user an option whether s/he wants to see the random photos in the front page of his/her page or not.
And before there are a flurry of responses stating this is undue censorship, please note the key word 'user _option_' - its not enforced - its your choice whether to enable it for yourself or not.
