ICANN has been able to get the registries of .com, .net, .biz and .info namespaces, to lock all pending-expiration Registerfly domains into a "Server-Delete-Prohibited" status for one month.
According to ICANN this will stop them from being deleted from the registry and being made available for re-registration by others.
ICANN says RegisterFly has refused to give them data about customer accounts, so they are going to court on March 6, 2007 to force Registerfly to do it.
There are more details on this very serious situation. Here is a link to an article with more information
