You can post images using Markdown but the images themselves have to be hosted elsewhere.

Ah I see. That's easy enough, though I have found people nowadays find that to be too much friction. Old timers are good with it as that is all they had on IRC assuming DCC was disabled as it should be. The current generation expects files to be hosted by the same platform.

In terms of memory the one thing I would want to avoid is swap. Slowness aside it is on disk and data can be recovered from it and automating mounting encrypted swap adds a weakness as well. ZRAM can add some compression to memory. [1] I think your idea of pruning replies matches the current pattern used by sites with space restrictions. Great work, I hope more people follow in your footsteps and also contribute to your code.
