Maybe you don't know but demonoid.com is site where it's not easy to register and registration are closed at the moment. It's owner(s) open registration 1 or 2 day per mounth, but I'm very "lucky" and always miss that days, so that's why I'm asking somebody who is already registered there.
You don´t need to register ; )
I have downloaded many torrents from there and i´m not registerd. A simple trick, or maybe not.
Install the Bittorrent program Azureos (i don´t have it install now, so i´m gonna talk from memory here).
This is what i´ve used to do:
I think that you can read the forums where the torrents are uploaded. Go to that forum and with your mouse copy the file hash information (ex: 834D2697E9405DA811CACB7384B467701848D66B). You will not paste it anywhere.
Now, when i did this step i went to Azureos and choose the option add torrent. Then you choose the option (i really don´t know it´s name) but it appears a place for internet track adress or something like that. Since i already clicked copy with my mouse on the harsh information, Azureos by default already had that window filled with some internet adress.
Click OK and Azureos will look for seeds to download the complete torrent file. I know that Azureos is known to have this option, but this allowed me to downlaod everything i wanted without need to register the site.
NOTE: Sometimes Azureos says that he couldn´t find the torrent. Try again later or on another day.
I have never needed to fill those internet adresses in Azureos. For some reason i just do a copy of the harsh file and he will fill it himself.
Try and then say if it worked.
