I find this truly bizarre that people are still writing about this. Look at where you adverts were supposed to be, check the height. If they're zero, something has probably stopped that ad loading. You don't need a third party script to manage this.
I wrote this over 9 years ago: https://thepcspy.com/read/how_to_block_adblock/ and it's somehow still cutting edge.
Publishers need to realise that static spatial ads are a lost battleground. They'll only ever take that back with the most aggressive means. The format is dead because they broke it (eg allowing hackers to deploy exploits over it).
They either need to be mandatory and interactive ("How many sips of ice cold refreshing Coca Cola Zero did the model have?") or straight up PAY people to interact. Google manages this with surveys already.
