bmw.de banned by google

Google removed bmw.de pages from its index. Is was happend because those german pages used some unclean techniques to rise its pagerank, and to get there more people. By google problem was by using so called doorway pages, which are extremly rich in keywords, but contain no real content. And user cant see them, because he is redirected to another page. He dont know, that something bad had been done to him, but its really dirty to rise numbers of visitors by doing this. But, there is some difference between private persons and big company. And that is in fact, that google will return bmw's pages into index immediatelly after they remove those doorways. Normal user can hope, that his pages will be unbanned in about year. (But this is only, how i interprete official message, dont know if its true, and if for example bmw wont pay some money for its return to google.)
