Website is marked as "not safe" if any part of its content has images or text that could be related to explicit "not family safe" material. Neighboring such websites could be a dangerous sign for any webmaster who cares about SEO traffic. Often "non family safe" websites use tedious link building methods. It is not a secret that Google may apply sanctions because of low quality mass link building and if a server is full of websites that are potentially could be banned then sanctions could be applied to the whole server. If centrum.cz is found on this server theoretically it may be banned as well as all other websites on this server's IP.
