Where to find 'the rules'?

Hi all, thanks in advance

I’m just starting a social network.

  • I’ve never done anything like this before.

I’m aware there are probably an ‘accepted’ set of rules that is sensible to get users of the network to agree to when they sign-up.
I have no idea what is sensible and what is not.

Any idea where I could obtain sets of rules for this purpose?

Thanks

Thanks, but I’m looking for a recommendation from someone with experience.

  • rather than in-experienced me taking a best guess.
