When the "UK & Ireland Only" option is set American questions and answers are still there. This is very annoying when it is on topics like Motoring, Law and technology, because the US and UK/EU laws and electrical standards are so very different from each other.
It can provoke illegal activities (eg gun use in the Law and "sports" sections) and be positively dangerous when Americans are answering an EU question about connecting electrical appliances.
I suspect it's because the US Answers section defaults to "All English", which is rather contradictory to the purpose of providing national settings, and Americans don't bother to change them.
Sometimes it is good to have an international forum and contributions, but sometimes it is a significant annoyance (as mentioned). It is right to have a choice.
So what is the point of these national filters if they don't work?
A knowlegable answer from a member of the Yahoo Answers team would be appreciated.
