I wrote a script to transfer my old blog items to blogger.com by blogger API. after transfered about ten items,server tell me following: For anti-spam verification purposes, please login to Blogger.com and create a post on your blog. You will need to solve a CAPTCHA. I followed the instruction, posted a new item manually while solving a CAPTCHA,but the sever still keep give the same error message. I posted again and again, my program still can't work any more.always be blocked. What's wrong with blogger.com? how can I solve this problem? I have about 100 items to transfer.
