Bux.to was added to the list because the Sohanad worm seems to contact that domain.
Bux.to asked us to reconsider the listing, and, after further review, we determined that the traffic to the bux.to domain was not malicious.
Therefore, the domain was delisted.
Remember, if there are any domains which you believe should not be listed, check the domains.txt file and determine why it was listed. Then contact us at email@example.com (remove all numbers) and constructively state why you believe the domain should be delisted.
Review and (if necessary) de listing usually takes less than 24 hours.
