I am on Firefox PC Win8, I don't even own a phone with internet.
Hasn't happened tonight yet, last night was another IC markets ad identical to Paul's, plus one ad for VE & VF Commodore suspension parts (hence based on my search history circa 3 months ago)
I post the images since its strange there isn't always a general theme, but its often the same ads, with the occasional targeted (this isn't one of them though)
It may not be advertising on ODK that is the problem ,marketing companies use cookies that track wherever you go online and send ads to your computer ,that's why I mentioned previously to delete your cookies or the use of adblocker.
