Comment spam example

Blogger.com already Strip links from comments, but spammers are so keen to do the comment spam just only to flood the comment of blogger. So, I got kind of announcement with titled Women's track & field throw teams. Interesting post yeah.

So, I go to the comment site of the post and delete it from the post. But I decided not to delete off fully the spam comment and keep as a memory in my blogging life.. hehehe….

Deleted Comment

Without wasting my time but I still considering to let Anonymous post some comment on my post, I enable the comment captcha at blog setting.
How to enable? Below are these steps.

1. Log in to your blogger.com account and click on the "Settings" tab. You'll see a top navigator menu like this:

2. Click on the Comments sub-menu; scroll down until you see this option.

3. Choose “Yes” and save the setting by click on “Save Settings” button at the end of the setting page.

After enabled, when there is a user want to post some comment on your posts. They will see this section to verify the post is from “Human”.

Word Verification Section

Digg.com also have the same function when want to add a new story, the screen is quite funny by stated: “Are You Human?” as this is part of method to minimize the Spamming.

I am not sure this will block fully from attacked by the comment spam, but this surely can make these spammers have to work quite a bit harder to achieve their nefarious goals.
