So real question: I've changed mine a while back and removed all the vowels - not machine readable but still human recognizable. At one point they did have my actual name and I imagine they still do. What is to say they don't tune their search to include previous names used on a profile? I also remember last time I changed my name I had a hard time getting around their validation. Any hints on how to defeat that check using an alias? I just checked and it seems they have also limited the number of times you can change your name. Apparently I only have 4 changes left.
