In light of the discussion in the WIPO Report of the competing interests of
verifiable contact information vs. the desirability of anonymous speech, it
seems that the on-going saga of William Walsh vs. Jeff Williams
(reminiscent of the Mad Magazine series "Spy vs. Spy) seems to illustrate
that presently, if someone merely using an ISP account rather than a domain
name was sufficiently motivated, he or she could remain anonymous for
quite some time. Requesting verifiable contact info in commercial TLDs
would allow such phenomena as this one to continue undisturbed.
Perhaps un-popular political causes should hire Jeff Williams to get their
messages out.
