One of the best examples of this was with the Pokemon games, where the creators had tried to block offensive words in nicknames without realising that some of their own characters had names that trigged the filters by default. So for a while, you had a situation where players couldn't trade Cofagrigus, Froslass or Marshtomp on the GTS (Global Trade System) because the default species name set off the swear filter. Hell, in one case, one you got traded in game couldn't then be traded online, since the nickname the NPC used would trigger the filters and wasn't usable by players. It also shows the folly of trying to do this with multiple languages at once too, since the filters block anything with a name that's offensive in any language the games are released in. So in some cases, you see Japanese players blocked from using a name because some characters match a swear word that's apparently a thing in France or what not. Makes you feel sorry for the folks at Game Freak having to name these characters in the first place, or the translators trying to make them work in other languages. Imagine trying to name 100 new characters per game in a way that doesn't contain any unintentionally words in any of the 9 or so languages the games are released in...
