Oh I just realized I misread Jose-Marcio's comment that cta.br and
ita.br are not TLDs but regular domains under an otherwise two
level ccTLD system (.br). So I've taken them off the
two-level-tld list and moved them to the regular whitelist.
(Functionally there's not much difference, but it's good to
keep the spirit of the lists correct in usage.)

I'm not understanding how wildcarding would help. Can you
give an example?
The only thing I can think of is that the lack of a wildcard
would say that a (parent) domain was ok, whereas a wildcard
would say that subdomains (child domains) are spammy. Probably
that interpretation will seem wrong given some good examples
or further explanation. :-)
