It's only on mobile platforms and is due to the ad platform GON has chosen to generate revenue to financially support the platform. I suspect Google Adsense is their platform and depending on Google to filter out these malicious phishing attempts is futile, even though they state they will do their best to keep them out.
GON could switch to Chitika for ad revenue and support instead of Google Adsense for a solution, but since their IT is on a contract basis I wouldn't wait on that.
I have switched my browser on my phone from Google / Chrome to Bing and thus far have not had a single issue with this happening.
