So things are almost impossible to delete here, the modlog is public and activitypub (what lemmy integrates with) is not meant for privacy. I am concerned you revealed too much about yourself in one go like your age, location, where you go to school, hometown, even specifics about your parents. I do caution having better OPSEC on the internet in general. Lemmy is also very leftist, as in left to your democrats, you’ll find anarchists/communists/socialists here so you might want to understand these theories before diving into political discussions. There’s also not many (if any) who like corporate LLM here. Anyway, good luck here.
