Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I have many Tbs I want to download & don't have the space plus I don't have the $ to invest in large amounts of storage so I've been trying to learn about Seedboxes here and around the net and it seems like it might be a solution to my needs but I have so many questions.

Is a seedbox just for remote torrenting and moving files to and from your computer?

Can you logon to a seedbox and direct download files from a website into the seedbox?

Can you create torrents in the seedbox for posting to torrent sites?

Are seedboxes mainly for keeping ratios up on private trackers or do they also accept open trackers as well?

Do you have to worry about DMCA notices with a seedbox?/Can seedboxes see what you transfer?

Can seedboxes be used with a VPN for optimum privacy or is there even a need?

What are some of the best seedboxes which leave a minimal, trackable footprint & preferably use US currency?

Any helpful guidance would be most appreciated. Thank You!
