the MySQL Web Spam blogger

Hi, I want to tell you about something that probably has happened to everyone from the first day we connect to the Internet: SPAM!
Yes, there is nothing new. It so happens that today, while checking whether there were any new comment on the blog, I found they had two different people and published around the same time (a few minutes after the other). Where only expressed what they had found useful information. Oops ... What is not cool?

 
 
 I find it strange, because normally there is a comment every 2 weeks and exaggerating. So I started to see the profile of those who commented. I clicked on the user's name and great was my surprise when I opened the website of a company that manufactures plastic bags "Weird no? Then I did the same thing with the other comments and this time he knocked on the website of another company that a. .. How well do you understand this?

For over 6 years we advise our clients in the design and assembly of its Web sites, and now we have specialized in administration, Positioning, Promotion and Marketing Web pages (SEO). " A and ...

The question is: How did they do that? Blogger allows 4 ways to restrict who can and can not comment on a blog: only members, Google account users, registered users and any user. As you can see the first 3 options require that the user is registered or log on to something while the latter does not. In order not to embarrass his followers, many bloggers use the last option, that is, anyone can comment. When a blog is configured with this option, when posting a comment will show the following:

If you select the option "Name / URL" will appear with a form to put any name and a URL to be referenced by that name.

 Although, as you can see, is marked with 

attribute rel = 'nofollow'
used to that search engines do not take into account the link, no SEO experiments confirm that Google actually If you follow those links though probably not the same value. Read more at:

Now, if I wanted to do this to help rank web somewhere, ask me How do I find blogs with these settings ? For in this also helps Google. It happens that along with the "Name / URL" is set to discuss other anonymous user. This option makes the comment

start with something like "Anonymous said ..."

or "Anonymous said ..." or translated into other languages. So we can only do a search on Google for that phrase.

Y no son pocos los resultados...

No he encontrado ninguna opción que permita desactivar los comentarios por "Nombre/URL" sin desactivar los del usuario anónimo. Supongo que son cuestiones de diseño que solo Google sabrá.

Es todo por hoy... un saludo.
