.pw
.pw is the country code top-level domain for Palau. It was originally delegated to the Pacific island nation of Palau in 1997. It has since been redelegated a number of times, most recently by Directi, a group of businesses operating registrars among other Internet-related services, who rebranded it as the Professional Web. From March 25, 2013, domains under the .pw TLD are available to the general public.
Symantec released two reports in April and May 2013 claiming that domains under .pw tld were a significant source of spam e-mail. In July 2013 the registry announced that they had passed the 250,000 registration milestone within the first three months, after having 50,000 registered domains in the first three weeks.
