When a UDRP is filed and the registrar is served with the complaint, the registrar releases the registrant details to the complainant. This ostensibly allows the complainant to fully understand whether they should proceed with the dispute or withdraw it. If a single domain name UDRP is withdrawn before a panelist is appointed, WIPO would refund $1,000 of the $1,500 filing fee, retaining $500 as a processing fee.
For instance, if I believe ElliotSilver.com is infringing on my trademark and the Whois information is private, a UDRP filing might quickly show me the registrant is also named Elliot Silver, and I should withdraw my UDRP because it is not winnable. In this case, I would have paid WIPO $1,500 and would have lost $500 as a processing fee.
