I have set up recurring posts, but they are all posted with my username instead of u/automod. I have looked everywhere and I have no clue how to get u/automod to be the OP of a post instead of myself. Is this a discrepancy between new/old reddit? There isn't an option to change the OP of a post when setting up a recurring post. Or does it have more to do with how the subreddit wiki is set up?

For reference here is my subreddit, where you see that the stickied posts are both posted under my username, whereas on r/adhd, their "weekly win" sticky post has u/automod as the OP. I cannot find any information about how to change the OP of a post, and I really hope I'm not missing anything.
