No, that's a malicious thing. Like someone trying to commit fraud. This sort of misdirection is better described as DNS manipulation.
Anyway, apart from inconvenience, it can lead to all sorts of networking nightmares. Things on your computer, or whole network, can't easily tell that you haven't actually got what you wanted when you don't get true error messages.
It's a disaster waiting to happen, and there are far better ways to help users who've got an address wrong. Most web browsers, by now, let you search from the address bar. So, if you don't get the address right, you're likely to end at a *NORMAL*, and useful, search engine page that will help you find what you're after.
Apparently BIND and DNSmasq have options to filter out these bogus results. Google has open DNS servers that don't return spoofed results.
