A while ago, "Blogspot" the Google product for blogging which I use, made it more difficult for robot spammers to post comments on its users' blogs. Commenters have to prove that they are not "robots". At first the process was not too difficult. The commenter saw a photo of a house number, and had to type in the number in the photo. Then they upped the difficulty... now there are a series of pictures, and you have to pick out the pictures that belong to a certain category. One of my blogger friends has been complaining about the difficulty of trying to post a comment, especially when trying to comment from his cell phone. On a small screen it's impossible to see the photos.
Well, I think I have found a way around this game. At least it has worked for me when commenting on "Blogspot" blogs. After I write my comment I click on "Preview". Then on the "Preview" window showing my comment, I click on "Publish". The comment is immediately published without going through any photo rigmarole. I guess that "Blogspot" figures that if the commenter wants to preview the comment, he/she must not be a robot.
So if you would like to comment on my blog, but are tired of going through all the hassle, try this method. In fact, right now, I am going to sign out, and then try to post a comment as "Anonymous" to see if it works on my blog.
