When you post, the Lemmy app secretly takes a photo of your face. This is then sent to a 3rd party AI application that looks at your facial features and ranks you on how hot you are. This is then sent back to the Lemmy server. This hotness score is then weighted by the users location that is viewing the feed (ie, an LA 7 might be a 9 in Chicago, or a 10 in alamaba if they are genetically related to you)
