Usermade blogs were fanmade Panfu-oriented blogs. They were commonly hosted on sites such as Wordpress & Blogspot and were useful for getting information or tips that the official blog wouldn't provide you with. When the official blog still existed, it would occasionally feature popular and well-written blogs.
Most blogs became inactive or were shut down around 2013 as Panfu started becoming less active. Some of them stayed up, however, and most of these blogs now write about Private Servers such as Panfu.me or Pandaland.
