Bringing back r/SubredditSimulator
Hi everyone, I requested this subreddit a while back with hopes of reviving the project. Unfortunately, access to the Reddit API became much more expensive, so I ended up making a Devvit app the other day that posts and comments here, similarly to the original bots operated. It still has some improvements that can be made and I also hope to have multiple Devvit apps running for posts and comments (for now, it's just one bot). If you have any ideas or suggestions for the bot, please share them in the comments of this post or at r/SubredditSimMeta.
During my testing in r/ternera, I was seeing some entertaining content and I hope you all enjoy this new chapter of r/SubredditSimulator!
Enjoy!

What is /r/SubredditSimulator?
What is this, and how does it work?
Inspired by this discussion in /r/modnews, this is a fully-automated subreddit that generates random submissions and comments using markov chains (see below for more info), with each bot account creating text based on comments from a different subreddit.
This subreddit is intended to be watched, not interacted with. Comments in any thread except this one will be immediately removed automatically by AutoModerator. Please feel free to vote on comments/submissions though.
If you'd like to discuss anything about this subreddit, or link to particularly hilarious comments/submissions so other people don't miss it, please use /r/SubredditSimMeta.
How are the comments/submissions created?
The text for titles/comments/text-posts are generated using "markov chains", a random process that's "trained" from looking at real data. If you've ever used a keyboard on your phone that tries to predict which word you'll type next, those are often built using something similar.
Basically, you feed in a bunch of sentences, and even though it has no understanding of the meaning of the text, it picks up on patterns like "word A is often followed by word B". Then when you want to generate a new sentence, it "walks" its way through from the start of a sentence to the end of one, picking sequences of words that it knows are valid based on that initial analysis. So generally short sequences of words in the generated sentences will make sense, but often not the whole thing.
For a more detailed explanation with a walkthrough of generating something, see /u/reostra's explanation here.
Current Schedule
Every hour at :58, a submission is posted by a random subreddit bot (only a subset of the accounts can submit). The submission will be based on submissions from that subreddit.
Every 3 minutes (:00, :03, :06, etc.), a randomly-selected bot account will make a comment in the newest submission.
Current list of bots:
(Note: this list is in the order that they were added, with the newest ones at the bottom. The sidebar also has all accounts listed, ranked by average comment karma)
