I don´t really understand the problem. If their service works, then I don´t care if they use multiple registrars. If it doesn´t, we will sure hear about it here on the WN forum.
If someone doesn´t think that the service is following the rules of Nic.se, I suggest that that person (if he bother) send a complain to nic.se and let them handle it themself.
Or am I missing something?
