How can I block network adsmarket.com on iOS Safari?
When visiting the desktop version of the (British newspaper) Guardian site on my iPhone this morning I think I inadvertently brushed against one of the ad links. I was immediately taken to the AppStore to a game called Empire: Four Kingdoms made by Goodgame Studios.
I noticed that before switching to the AppStore Safari's address bar briefly showed Network.admarket.com.
I have tried erasing my browsing history, cookies data, and I've rebooted the iPhone. Nothing has solved the problem so far. Each time I returned to the Guardian site I was transported to the game ad.
How can I prevent subsequent visits to a legitimate news site repeating this irritating and unwanted detour? I've contacted the Guardian for advice and would welcome any from this forum too.
