I have pre-registered (I know it is 90% useless ) but this particular registrar is blocking names which have already been pre-registered
This FAKE .eu registrar is only blocking domains that have been "pre-registered" via itself.
The sunrise period tends to lessen the rush when the general registration period starts. However it may be a good thing, once properly accredited .eu registrars are created, to pre-register via a number of registrars to increase the chances of getting the domain you want.
