Just a comment about membership on websites, Difficult to sign up?

I tried to sign up on the youtube site. I put in my name user-name and password. The user-name was in use, I changed it. The password wasn't hard enough, I changed it twice. Then they wanted me to copy a bunch of letters so they know its a person. They screw the letters up so they are hard to read. So much so, I had to do it 3 times.They should make it so humans can read it. I ended up having to change something 6 times and still didn't get it right. This isn't a bank or a home loan I was applying for. Its a video website. I just don't understand the security for a website that deals with unimportant stuff like cute videos. I have a new rule. If I have to change something 3 times I just wont sign up. What do you think? Have you had similar problems?
