So remember and someone has to tell Jim this, all it takes to eventually take down 8kun, is one connected browser that gets a bad URL for an image ad. Most likely people let that reload button spin, indefinately or do not reload the page until the get a good ad loaded. I hope this is clear, this is 8kun's only real problem and has been the cause of many:
Flood Detections
Broken Images in page
Server unavailable from the NGINX server
Long waits to see posts
Crashed and frozen 8kun and image servers.
