Picture this, you read a new subreddit rules thoroughly, scanning to see if your topic you have in mind is in anyway a violation of the rules, you find its not, the rules being fairly standard, like "don't be an asshole" that kind of thing. You make long, detailed, thoughtful post, relevant you think to the subreddit. You hit post and wait for no doubt an auto bot, there's a 50/50 chance that it will remove your post automatically, when that doesn't happen you think hey, look at that, this post might stick. Yet moments later, a "banana" removes it, the post you made thoughtfully doesn't quite meet standards for whatever reason. Maybe you misunderstood the sub altogether. Maybe the bananas are flaunting their power, whatever it is, its frustrating to no end. Anyway, that's my rant for the day. Hopefully, this post doesn't get auto deleted.

Edit: ironically, it was auto removed for a certain word, which I've now subbed with "banana"

Edit 2: this is no way encouraging um, revengeful, behavior to any subreddit, ultimately I don't care, its slightly frustrating and has been my experience on reddit lately.
