Because most of the people on Lemmy are refugees from reddit and nowadays on reddit, if you are not a porn focused sub then they require you to censor every damn thing or face getting banned from that particular subreddit, getting banned from several subreddits depending on who’s modding and how many subs they are modding and how fucking stupid their bots happen to be, or getting banned from the entire site by the admins on their particular whim for that day/week.
