A big thing about running large online communities (on Telegram, Discord, wherever) that so many group owners don't realize:

If you want your group to be successful long-term, you have to understand that if you try to please everyone, you will end up pleasing no one. Do NOT create a group chat if your goal is for everyone to like you.

You will have people who balk at your rules, who say your rules are stupid, who complain that "well, OTHER chats let me (x, y, z)." You WILL have to ban people. You WILL almost certainly have to ban people that you LIKE. And you will have a reputation among people you've banned as a "narcissist" with a "personality cult" and "white knights." You're going to have banned people call you a bully. You're going to be accused of dogpiling. You're going to have to deal with spurious callouts, and hateful DMs out of nowhere. You're going to have banned people getting together and setting up competing chats because they don't like how you run yours - that's healthy. If they can do something well that works for other people, they're out of your hair and folks have options; everyone wins.

Facilitating a community space is not something you do to feel validated or to make people like you. It's something you do because you want to provide a space for others to be themselves - but that doesn't mean that you can just let people walk all over what you're trying to build up.

You're going to make mistakes. You'll occasionally ban someone too quickly. You'll occasionally let someone get away with way too much before banning them. You'll get attached to a particular rule even though it no longer serves the interests of the group. You'll get "rule creep" as you try to make different rules to account for every contingency. These are all things that can be fixed, most of the time.

A lot of people want to run groups where "everyone is welcome!" But there are going to be times when you have to stick to your guns, even if it means disciplining (including banning) people that you like. And not all of them (in fact, few of them) will react to that with understanding. If your goal is "no one is excluded," you are doomed to fail from the beginning because in a large community, you're going to have people who disrupt the group's harmony - and refusing to exclude them will give THEM control of the group instead of you. And a group that operates on constant disruption is not attractive to anyone.
