Welcome to WebmasterWorld Guest from 188.8.131.52
Many domain-name registrants are receiving "Domain Dispute Notification" mailings from an entity identifying itself as "XChange Dispute Resolution."
The mailings FALSELY state that XChange is an "ICANN authorized arbitrator" (they are NOT) and that the registrant must mail in a "security deposit fee" to defend ownership of the domain name.
A scanned copy of the deceptive mailings is available at:
Registrants who receive the notice should contact an appropriate governmental law enforcement/consumer protection agency to report the incident. You should NOT send money as requested by this notice, as this is a complete scam.
Me again. I hope this helps someone. Forewarned is forearmed.
