So.. if I want to help and seed the torrents, do I have to download the whole 80-120 TB for this? can I somehow help when I don't have a space for hundred TB on my machine? went to the website but didn't find a guide or anything else on how to do it

Not entirely sure why this was dead. This is the answer to GP's question.

Thanks, was looking for something like this. With all the hardware I'm sure is sitting idle under HN users, we could make a big contribution for ~free.
