Yes… What you are doing is fine. The main reason why we say not to share the .torrent files is because they contain your personal passkey, which can compromise the security of your account.
That being said however, submitting the .torrent files and the contents to a seed box in order to help share the content with other users is perfectly acceptable. Also, there is nothing saying that you cannot use multiple IP addresses (as I use at least 2 myself on a regular basis). The only thing is that you cannot use more than one account on the same IP address, so as long as you're only doing things with your own account, you're in the clear.
