Reminds me of a project i stumbled upon the other day using various services like Google drive, Dropbox, cloudflare, discord for simultaneous remote storage. The goal was to use whatever service that has data to upload to, to store content there as a Filesystem.
I only remember discord being one of the weird ones where they would use base512 (or higher, I couldn't find the library) to encode the data. The thing with discord, is that you're limited by characters, and so the best way to store data in a compact way is to take advantage of whatever characters that are supported
