I think it is actually the proxy server NGINX that is cancelling the web server requests because it sees it is out of resources. That happens because it spends all of it's resources looking for bad urls for images from posts. In reality, one anon no loading the bottom ads, can wipe out both the web server and images server, by keeping them in an endless cycle of ping pong of request bad image url A B A B A... until all system resource, meaning ram, does a stack overflow, but actually the proxy server stops requests before it gets to that point by cancelling the web pages to give the web server more time. But more time won't do it, because it is an infinite loop.
