I just checked my newest links and I found some links which are absolutely weird the sites look like this: madgestrassburg.xyz the content is German but it is abolutely senseless. It looks like automatically translated. It is adult content about sex etc. the anchors of the links going to my site are obscene and the link neighbour hood is very bad the links go not to my site only but to hundred of sites. I found also some competitors at the moment I find 10 sites but they all came in the last couple of days. It might become more Can you please help me: What is this? Is this a negative SEO attack? If not what is the purpose of these sites?
