By passing no follow in blog comments?

[nikoman]

I have seen some kind of spam where the spammer apparently has bypassed the nofollow attribute using some kind of trick that tricks the regular expression engine of the CMS.

Check the comments from this site:

You may notice all comments are a spam and the HTML code is stripped except the email which is shown as do follow. Does any one knows about this technique?

email links are most of the time set to DO-FOLLOW cause it is never used for spam link building anyways.

Have you ever programmed anything? The detection system wont mind it only rebuilds the URL using the data after the href no matter whether it is a mail or valid url it adds the no follow. Make a test in one of those blogs that I posted placing a email and it will add the nofollow.

NEVER MIND! I will share the code when I figure out how it works.

Happy new year

Wordpress probably just automatically links email addresses. They dont add nofollow to them because it doesn't matter. Nobody cares about spamming an email address.

You figured something out?

Seems like they are trying to bypass the no-follow attribute by adding a email address at the end of the URL, but it doesn't work because link is not clickable.

I am still trying. It is possible to do it but I still do not know what code they are using. They are trying to mock the regular expression engine of PHP so wordpress may not recognize the URL and leave it as is without adding the nofollow attribute. I have spotted a lot of blogs with that issue.However, they are unmoderated.

The url is not clickable but the email does. Now switch the email with the url and the url is clickable, another thing is that these blogs are not autoapproved. Some how they managed to put the links.
