iPhone pop-ups

[Imurg]

I've been getting a few words underlined and highlighted in blue in many posts today.
If I hover the cursor over them an iPhone ad pops up. I haven't clicked any so don't know - and don't want to know - what happens next.
Is this part of the Forum Advertising thing or is it a Spammer getting into the works...?

They seem to be intermittent
There was one on Rick's Board thread but when I went in the 3rd time it had gone, same with Kid's Finding a Way thread....

It may be browser related? I only use chrome on my iPhone, never seen the links. Just checked the kid thread as well.

Hmmmm perplexing.

Its an adware bug called "Coupon Drop Down"

Local to his PC, panic over, nothing to see here, move along
