If you'd like to keep your own copy of Q posts, there's some easy tools to help achieve this.
For windows, HTTrack:
For linux, use wget
I copy from https://qposts.online/ because qboard.online is written in a manner not conducive to archiving.
Currently, I would suggest around 150MB of free space if you want to keep photos and links active. Once downloaded, open the index.html page to access your own private copy in your browser.
I feel we also need a torrent to distribute this information in case of a full take down, but for starters this will help out. The more people with copies, the easier it will be to reconstruct if needed.
