Uploading movies and soundtracks to gobblin.se

Is uploading copyrighted material on "gobblin.se" actually legal? I'm asking this 'cause I want to upload my whole A/V collection containing various movies and soundtracks (around 1TB and more), and don't want to mess with the server storage, or worse, cause a Court roundup resulting in a temporal website shutdown (I do appreciate the website owner who gave us the opportunity to experience this fantastic piece of free/libre software and just doesn't want to cause him difficulties). Another question is whether the uploaded data will be preserved and for how long (since my uploading speed is slow, and because this takes a lot of time and work, I would not like to see that after some period of time, some or all of my uploaded files was automatically deleted).

I know that I can create my own MediaGoblin server, but I want a temporary solution until I get some money to make one (not something that I can accomplish in a short scope of time). I also know that this can depend on geological restrictions, resp. on local laws, and there is no difference if I upload something to, for ex. a file-hosting website (and share the link or links with people), or a video-sharing website like gobblin.se.

Since I doesn't found any legal information on the site itself, any help in this regards will be appreciated.
