url-filter useless against google?

Hello Users,

I wonder myself why a google-ad can reload inspite of having the domain 
doubleclick.net freshly blocked  having this url

https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-1274416353693598&output=html&h=250&slotname=8842703660%2F3875420540&adk=228340318&adf=298697960&w=300&ea=0&flash=25.0.0&url=https%3A%2F%2Ftaz.de%2FAtheist-ueber-Freiheit-von-Religion%2F!5400954%2F&wgl=1&dt=1492243233483&bpp=23&bdt=3126&fdt=33&idt=646&shv=r20170410&cbv=r20170110&saldr=sa&correlator=355103459859&frm=24&ga_vid=1556901083.1492243234&ga_sid=1492243234&ga_hid=1762100579&ga_fc=0&pv=2&icsg=2&nhd=3&dssz=2&mdo=0&mso=0&u_tz=120&u_his=1&u_java=0&u_h=1080&u_w=1920&u_ah=1080&u_aw=1920&u_cd=24&u_nplug=1&u_nmime=2&adx=0&ady=0&biw=-12245933&bih=-12245933&isw=300&ish=250&ifk=3441873982&oid=3&loc=EMPTY&top=https%3A%2F%2Ftaz.de%2FAtheist-ueber-Freiheit-von-Religion%2F!5400954%2F&rx=0&eae=2&brdim=%2C%2C0%2C27%2C1920%2C0%2C1920%2C1029
