I have a Linux Server that I manage with friends at work, and on it we've a Wiki that we use to share informations.
Yesterday I went to see the Recent Changes and I saw that a page was modified... I went to check the modified page and... surprise... the page is empty with links like http://www.gccgle.com/webs/00/ 00, all links to different pages from the same site. Curious... what is this? Who is this URL?
I decide to check what is this site... surprise (or not!): the site is a society specialized on search engine optimization (SEO), alias spammers for Google.
What are these? These are bots that place on the net links to sites that must be promoted only to advance the rank of the site on search engines like Google.
The Wiki are the new way... Wiki are free to edit for nature (they are collabourative site), and for these bots is quite simple to have a script that search for a Wiki and place series of links on the pages. Not good... spammers have no limits.
Obviously, I've removed all these links from the page... now I'm waiting... I think that between some days these links could appear again...
Not good!!
