I don’t know what kind of comments and posts you’ve made on Reddit, but if any of them are technical how-to’s or something that may come up when people search for specific problems, then it might be good to leave those comments, or else just prefix each comment with your “purged” message instead of overwriting them entirely. I mean if it’s fun memes or discussions, then you do you 😅 I’m just thinking of the tale of DenverCoder9. Plus, it probably costs more for Reddit to store a longer comment than a shorter one! Pennies or less, but still!
