Be very careful with this. I know that test.de and invalid.de
are okay, but generally you can't fix all silly abuse ideas.
It's better to support 2606 (example.cno, *.example, *.test,
*.invalid, *.localhost). For the TLDs that's no problem, you
already know that example/test/invalid/localhost are reserved.
And *.local isn't better (but not officially reserved).
But something like say local.tv, who knows ? Maybe they are
spammers, maybe they don't exist, maybe they are okay. One SLD
rarely or never abused might be NIC.* in all existing TLDs.
