Adult webmaster against the ICM proposed .xxx tld
As an adult webmaster (been in the industry for over 9 years), I can only see disadvantages.
First of all the proposed .xxx tld will do NOTHING to keep children safe. The only effective way to control what your children get to see on the web is white-listing, not black-listing. So creating a .xxx tld in the hopes you can block it to protect your children doesn't make sense.
There are 1000s established adult sites out there using .com domains. As long as those exist, it will be impossible to block porn by blocking sites in the .xxx tld.
And no one in the adult industry has any intention to abandon their established sites. Why would we destroy our own investments?
If you really want to protect children, you might want to consider setting up a .kids tld, with nothing but sites aimed at children. That way, parents can block everything except the .kids sites.
Second, The adult industry never asked for the .xxx tld. In fact, adult webmaster have been and still are fighting AGAINST it. The .xxx tld was proposed by the ICM, a private organization with no ties to the adult industry and with only one goal: making money off of adult webmasters.
