There's a risk that disgruntled ex-redditors will collectively vote for the most terrible people they can find for mods, just to harm reddit and drive people here. That would be truly sad to see. Truly sad.

Edit: other appalling things I hope we don't see are people going to reddit in down times only to upvote bad comments and posts, and downvote the good ones.

The very last thing we would want to see is the mods of large subs switching between private and public mode too often, because that apparently has to change permissions on all the posts in the sub, and was why reddit had downtime when they all went dark. They may even have the wild and outrageous idea to briefly turn off private simultaneously, only to go back private as a form of malicious compliance with Huffman's warnings.
