I was thinking here of people who have been shadowbanned, and enemy social media companies which take down, hide, or push your posts into your private folder. I hope you all are backing them up on a hard drive, maybe a flashdrive(sometimes easily corruptible though), besides on your own computers and the cloud(which I hope you store that encrypted there).
I especially would like for you to consider the IPFS(InterPlanetary File
System) storage, a decentralised way of storing your files/posts.. Also, consider storing on torrents, such as bittorrent, etc for examples. Beware to the unaware, of course, IPFS and torrents aren't anonymous networks.
