“NEW YORK - The online advertising leader Google Inc.
said Friday it would help make it less lucrative to tie up millions of
Internet addresses using a loophole and keep those domain names from
legitimate individuals and businesses.

Over the next few weeks, Google will start looking for names that are repeatedly registered and dropped within a five-day grace period for full refunds.

Google’s AdSense program would exclude those names so no one can
generate advertising revenue from claiming them temporarily, a practice
known as domain name tasting — the online equivalent of buying
expensive clothes on a charge card only to return them for a full
refund after wearing them to a party. . .”

“. . .Name tasting exploits a grace period originally designed to rectify
legitimate mistakes, such as registrants mistyping the domain name they
are about to buy. But with automation and a burgeoning online
advertising market, entrepreneurs have generated big bucks exploiting
the policy to test hoards of names, keeping just the ones that turn out
to generate the most revenue.

The practice ties up millions of domain names at any given time,
making it more difficult for legitimate individuals and businesses to
get a desirable name.”
