You should remove the tag. Since they have changed their domain officially so it does not deserve a tag.
Done. Feedback changed to neutral with info for domain change, but they should inform people in bitcointalk forum and change all links to new one if they want to avoid problems.
Great. It was a quick response. thank you.
Btw
sdice maybe forgot that they have a thread here also. It's normal actually as a human. but they should be more professional and active. Again they also did not notice your neg feedback, if so they would come here.
