I usually don’t get a lot of traffic for this ad group because of its tight targetting. Today I got 3K clicks, from many different carriers and mobile OS. Strange thing: I edited the URL and the clicks were still coming even if the ad group status became “Pending Review”.
Only pausing it stopped the random traffic. Basically I wasted more than $150

Did it ever happened to you ?
What would you do in this case ?
