I have taken some time to compile the list of poor performing ad networks (including native ad networks) with the lowest cpm cpc. Not only that, they have a very poor prospect of generating any meaningful revenue coupled with other factors like ad quality, malware-prone ads, spammy ads, spammy links, link redirects, exploitation, poor customer service, no customer service, bad user experience, bad reviews from publishers, and more.
This list is by no means exhaustive and in no particular order. Most of the items in the list have been trialed by myself and are based on my own personal experience. I will continue to update this page as I come across more ad networks that truly sucks, yes they sucks!
