Personal Information and Security
What this means is, that we will be deleting our log files monthly, that keep track of your pages visited, and your IP addresses. While this information helps us track down multiple accounts and cheaters, at some point in the future that information could be requested by some bully corporation, and if this ruling is any indication, we'd be required to give up your personal information and your browsing habits to that corporation.
To keep it simple, it means that we're protecting your privacy, and making it harder for large corporations to request information about where you've been looking on the internet.
If you share a computer with someone else, you're fine! Don't worry about it :)
But thank you for informing us anyways 
Slushie: A larger company forced youtube to turn over all the logs it had of member activity and all videos they've watched. While it's only been for youtube so far, it could soon become for everywhere online, so as a precaution and to save the hassle, the Subeta staff are emptying the log file every month now.
