Reddit used to be open source. There is still a copy of that source available on github. It’s 7 years old so it’s probably significantly different from what they are running now. Still, it gives some insight into the design.

For example, deleted comments aren’t deleted, it just sets a deleted flag. Example code that shows this.

I haven’t dug around the code enough to figure out how editing works, it’s Python code so an unreadable mess. The database design also seems very strange. It’s like they built a database system on top of a database.
