Not to forget Alexandre Khalil <alex@leb.net>, who lets me run large series of queries on leb.net servers and who feels the heat from admins around the world who think that someone tries to hack their servers. At the moment the complaint rate is about one complaint every 150000 hosts queried :) Thank you Alex for your support.
