Blah Blah Blah.
I'm well aware that the Government or hackers* could compromise Slashdot and find out who I am. I also don't care. I can also lie to you about who I am on Slashdot. Assuming you use the handle "Kenja" on any other online forums I can probably show you fun-filled research papers from people who are really good at data mining who could probably track you down with a very high probability just based on the content of your publicly-available posts and some educated cross-reference guessing. It's life, deal with it.
*Slashdot still runs on Apache 1.3 you know, and the "infrastructure" if you can call it that hasn't been updated since the late '90s. It's been compromised in the past and I feel that hackers don't bother with doing more damage because there isn't any money in it.
