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.
Allow me to shed some light on that…We are currently in the process of upgrading and moving our servers. During this process, the site may seem slow, or even generate random database errors. Please be patient with us while we complete this process so that we can better serve our users with the optimal speed and reliability that they should be able to expect.
I don't think that there's really any set way of being able to tell how many unique users that we have given that some user accounts aren't active, some are duplicate accounts that are now just sitting in limbo in the system, and some accounts even are test related accounts that staff have… So.... Getting an actual number may not be the easiest thing to do. As far as I'm aware, the number the last I saw was over 10,000
Yes, they expire after a few days and they are lost.
Your friends should look into the spam, especially when using Hotmail, Outlook, Live or Gmail.
Gmail users best look for spam on Gmail's WEBMAIL interface under "Others…" in the left navigation bar.
If your friend missed the invitation, write the helpdesk.
