I pay also, and I still get ads, that is why I use uBlock Origin and Ghostery .... yes I pay for no ads and I still get some, but I don't complain, I get even!
This is not the only site I pay for "ad free" and it's not really true. Part of life. I need the blockers for other sites so no big deal.
Honestly, I am sorry you guys have Safari and Apple and thus limited capability, can't help you there.
There are 10 times as many computers running a version of windows as compared to Apple computers running MAC OS.
I have a hard time finding the ratio of Windows programs vs Mac programs but I suspect it is even wider.
So, sorry guys, but I would suggest going to FireFox on your Macs and then getting some good popup and malware blockers.
Ghostery is available for Safari, and you must be able to find a popup blocker too... It can be done.
