I started getting 404 hits on humans.txt and did a little research. This is a file similar to robots.txt that allows the website authors to leave their imprint. I don't know why anyone would try 55 times in one day to located it on my website, but I suspect it is because some of the authors are leaving their e-mail or twitter addresses on the humans.txt file and robots programmed to scour the net for e-mail addressed to be used for nefarious purposes have their attention turned to it. No format seems to be necessary, but to prevent 404s you might create a little file for the robots to find (leaving off your e-mail address!) best regards wiz
