I have a free blogspot and put some free articles as a content. After the second post ( I have mentioned the source and author), blooger make me enter a validaton code in order to post again. it means that I wouldn´t join adsense in the future, doens`t it? and on the other hand this blog hardly be indexed in google searches? Thanks
I doubt that's the reason you were asked to enter a captcha. Thats what it was right? Partially Scrambled text? That was probably to prevent content spamming by automated scripts. I doubt you have anything to worry about.
