They probably won’t if it’s individual people, though they are donation funded so if they show their supporters that they don’t care those supporters might stop financially supporting lemmy.world. So telling them they should just leave because you don’t care or handing out petty bans like “let me help you” isn’t going to inspire these people to continue contributing donations.
This website doesn’t make a profit, but that’s all the more reason there should be an effort to not make people hate them, because I don’t know anyone who would enthusiastically donate to support people or an organization they hate.
