A script to copy posts from one subreddit to another.

Project description


This is a simple script which will copy posts from one subreddit to another, ideally used for copying posts to a private subreddit for bot development purposes. It requires you to be a moderator of the subreddit you are copying posts to, and allows you to choose, along with the source/destination subreddit:

  • The sort method of the posts chosen (hot, new, controversial, and top)
  • The time frame to grab posts from (day, week, month, year, all)
  • How many posts to grab
  • Whether or not to include the comments from the post you mirrored (this functionality is very time consuming)


Whenever I create reddit bots, I would normally manually create posts that mimic the posts I would expect when using my bot. This becomes tedious, especially as the bot grows more dynamic over time. Instead, I figured I could write a script which would do this tedious work for me, and as an added bonus, the content would be real data from the subreddits I would be targeting.

Can't you use this for spam?

I suppose so, but you shouldn't. This script includes a simple check to make sure that you're a moderator of the subreddit your mirroring posts to. Although this is easy enough to remove, I figured that anyone who'd want to make a spam bot could and probably would have without much effort.
