It is a damn shame, as this has been one of my most trafficked mobile sites, but I won't be coming here anymore on my phone. The ads every 2-3 posts are too much. I know the site needs to make money, so I donate. I am not going to participate in a huge ad wall.
I might come back on my computer, but only with ad blocker.
This has been a known problem for a long time. It's a feature, not a bug.
