I really don’t like having “deleted” flags and such on database records. I thought about using elixir processes to schedule a deletion with :timer.sleep, and sending a kill message if the user clicks the undo button. Are there obvious drawbacks to implementing “undoable” actions this way?
# Schedule the deletion
pid = spawn(fn -> :timer.sleep(10_000); Posts.delete(post) end)
# User clicks the undo button
Process.exit(pid, :kill)
Where Next?

Two things jump out at first glance:

Yeah actually I’m thinking, especially because of the nature of the application, it might be better to change the logic to something more similar to “hide from feed” or “archive.”
As a side-note, is there some way to prevent the second case from happening without persisting the actions to disk somehow?

Not really no.
More to the point though, I’m not sure that the code here does what you want it to do. It won’t delete the records until 10 seconds in the future at all, which means if your user loads the page in another tab, the records will still show as not deleted.
A more traditional way to do this is to have a
deleted_atcolumn that you set immediately toNOW()when the user clicks delete. If you want to actually remove the rows at a future point you can clean it up later.
