Be Identified

Now that I am responsible for my own infrastructure I am taking more notice of the risk of using specific methods. I was quite surprised, after changing my hardware, to start being challenged by Google's blogger. Many of you have probably seen the challenge, where you have to read a distorted set of letters, to prove you are not a sim, This is called a captcha. Last night this happened several times in a row. The letters I had to read were so distorted I had to try several times. I felt somewhat put off by this. Am I a machine or human? Am I depending too much on Google's usually excellent services?
