AFAIR, China has been doing this for years, with variying degree of
impact on networks outside China:

It's extremely annoying that they also match substrings, probably to
block proxy services. Try: dig footwitter.combar @

Sadly, China is not a useful location for DNS services that are to be
queried from anywhere (IMO, YMMV, I gave up). I cannot anticipate which
substrings of hostnames are going to be blocked next and the problems it
causes are often unexpected and difficult to debug.
