The Daily Beast has an interesting piece on the nonsensical rules governing hashtag censorship on Instagram. The issues involve sex, race, and bodily functions. From "Instagram's Sex Censorship Is Inconsistent and Hilarious":
Many of the single word tags like #fuck, #bitches, #porn remain on the blocked list, but many longer variations, like #fuckfriday and #mybitches are now searchable. #Dildo and #chink were once banned but can now be searched, though #wet, #shower, and #popular remain blocked. Users can search #faketits, #underboob and #boobz, but not #sideboob, #boob or #boobies.
