Yes, believe it or not, Humble Bundle is on my shit list.
I bought a whole series of games. I go to the screen where you click on the link to download. Up pops a captcha box. I put in the code and hit enter and it doesn't log me in and gives me another captcha to do.
Well it doesn't matter if I do it in lower case, upper case, in FF or IE, logged in to HB and/or Steam, I keep getting the same result. No log in and another captcha box.
I've contact Humble Bundle several times and the only response I got was an email of how to use captcha.
So Humble Bundle is now on my shit list.
