Nxtgn (nextgen.biz), is shut down, and have send the following message on their twitter(english version below):

Kære NG brugere

Grundet den seneste tids megen opmærksomhed på NG og derved dens brugere, har vi valgt at lukke trackeren.
Dette sker ene og alene for jeres sikkerhed, da der de sidste par uger er kommet ekstra megen opmærksomhed på NG.
Dette har bla. betydet en større risiko for både vi i staff, men også jer som brugere.
Derfor har vi valgt ikke længere, at ville tage den risiko, at vi eller jer skal havne i en situation som ingen af os ønsker.
Vi vil gerne takke for den tid vi har haft sammen, med håbet om et snarligt gensyn.

Med venlig hilsen
NextGen staff

English version:
Dear NG users

Because of the big amount of attention! NG and thereby it's users have had, we have chosen to close the tracker.
This is happening for your security, as there the last couple of weeks have been a lot of attention on NG.
This have increased the risk for us in the Staff, but for the users aswell.
This is why we have chosen to no longer take the risk, that any of us should end up in a situation we do not wish.
We want to thank you for the time we have had together, with the hope we will soon see eachother again.

Sincerly
NextGen Staff
