…whose operator automatically adds private pages like those of my Abitur class (rmg91.de) (and seems to check only a part of the site for its description) – and then spams you with a “free route description” (and of course some adverts for more of his services)?

Especially if it’s the same company (www.cylex.de) that last year added a private address of mine that’s been invalid for years and mixed it up with the phone number and description of some other company?
