@leeneia - I hadn't come across Professional Web before, but it seems to be in the domain name registration business. It was available for general registration from March and registers .pw domains without any apparent restriction. .pw is a new top level domain, like .com, .org, etc.

They seem to be Dubai-based and offer domains via a large number of Registrars. They claim to deal with abuse via these Registrars, which means you first have to find the Registrar. There's some help via registry.pw/policies/ but I would guess that spam filtering would be more effective.
