Another thing worth noting....
Functionally, there is NO difference between "Low" and "Strong" for your privacy settings. Regardless of your settings, you will be shown as "Anonymous" to other users on all torrents. The only thing that becomes visible to other users if they look at your profile on the "Normal" setting is your ratio information such as overall ratio, upload/download totals, and SBP information.
Regardless of what privacy setting you choose, your torrent history is NOT visible to anyone other than staff. The only real difference between "Low" or "Strong" and "Normal" aside from overall ratio and SBP information is that if you have it set to "Normal", other users can see the button to PM you, add you to friends, or add you to blocks.
EDIT: Just to give you a visual, with my account, I have my setting set on "Normal" so that other users can PM me directly if they need assistance. When on "Normal", this is what my profile will appear as for a regular user.

The only "damaging" (for lack of a better term) info that is shown to other users when on "Normal" mode is my ratio, as well as my upload/download totals. Under Canadian law though, this is hardly "damning" information, as this does not link to any specific torrent, so it cannot (at least in Canada) be used as evidence that any given torrent was downloaded and/or shared in full.
Just to further provide an example, even with my profile security set to "Normal", when viewed from a regular user account, my information does NOT appear anywhere for other users, even if I comment on my own torrents.

See... I show as "Anonymous", even though my security settings are set to "Normal".

And when I put a test comment on my torrent, it shows to a normal user like this...
For the current moment, the only time my username on a torrent will appear to other users if if they use the button to send the uploader a PM, but as I said, that is soon going to change, I'm just not sure how.
So even with your profile set to "Normal", there is nothing (outside of the send uploader a PM button) that will show my username attached to any torrent I have uploaded, even with my security settings set to "Normal".
