We have been quiet in this thread since March. That's not okay and I'm sorry. This is the thread we asked you to report problems in, and then we stopped answering in it.
I've gone back and read the last few weeks. There are three different things being reported here, and they are not the same problem.
1. An ad opens and you can't get back. @M70AB2 described it again today - you land on a blank page reading about:srcdoc and the back button is dead. This one is real and we can see it from our side: in the last seven days we logged 781 of these, coming from 175 different people. That is not a few odd browsers. That is a campaign.
What I do not have yet is
which ad network is doing it. Our reports tell us it happened. They don't tell us who. That is the whole reason it isn't fixed, and I'd rather say that plainly than tell you we're "working on it" for another six months.
2. "Click the ad to continue." @ACHiPo raised this on the 1st, and we have a screenshot of it from the 29th. We checked our own units first - it is not our interstitial. It's coming in through the same door as #1.
3. The blank gaps, and the grey bar at the bottom. @Blue Shadow - the bar that eats a thread-title click until you scroll a bit more is ours, not a rogue advertiser. That one is our layout, and that one we can fix.
What would actually help. When one of these throws you out, the most useful thing you can post is
the address it sent you to - even a partial one off the address bar - plus roughly what time it happened. Keep the screenshots coming, they do help. But the destination address is what lets us name the network and cut it off. Without it we're looking for a fingerprint in the dark.
One other thing, since it came up: I'm still here.
I'll be posting in this thread every week from now on, good news or not. The silence was the worst part of this, and the silence was ours.
