Found a nice great tool from WB3000 which will check for you the registration of Demonoiddotcom and infom you about it.
If you dont know what demonoid is plz dont ask me
Checks for open registrations. Includes hidden timer mode, providing
checking at regular intervals.
For what i have read on the site actuel it is closed and will be back soon with open registration in case of backup troubles:


We will be back as soon as possible, but this will probably be a prolonged downtime.
Thank you for your patience

The site will return as soon as possible, but there was a problem that caused data loss and the person who can help us get the data back is not able to help at this moment. The site will return when we can get his help

A loss of a some months worth of activity including registered users and torrent submissions is to be expected because the backup we are hoping to get back is not up to date, so please be prepared for it
As you can read "plz be prepared for it"
