There aren't any standard rules that appear. Any rules that appear when connecting to a network are specific to that network and may be completely different from those on other networks. If you want to pick a certain network, you can connect to it for their rules or if you can't connect where you're at, someone here should be able to paste that network's rules. But you'd need to specify a network.
General rules that you see on many networks would include things like no bots (or a variation that allows bots that don't cause problems [aka non-abusive bots]), no spamming, etc. Most rules can be found on the networks' websites as well, though they may be worded differently than what you see when connecting.
Here are some rules from one of the Dalnet servers (additional rules for all Dalnet servers are in the /motd, which I don't have logged and can't connect to see right now):
- 1) The admin / operators of this server reserve final authority
- over your privilege of connecting (or remaining connected) to
- this server, up to and including adding your IP or netblock
- to our machine and/or upstream firewalls in response to any
- violations of these policies.
-
- 2) If we find you connected to IRC from any hosts to which you do
- not have legitimate access (e.g. drones, hacked boxen, proxies)
- your connection will be terminated immediately. Violators of this
- policy will be logged and their information will turned over to any
- applicable legal authorities.
-
- 3) Do not ask us for an oline. We will not give you one.
- REASON: we will never oper someone who can not follow simple
- instructions, such as "Do not ask us for an oline".
-
- 3b) We will not provide you with an oline or any other form of
- access in exchange for money. If you ask, we will consider
- that to be dishonor and an insult to us, and you will be
- klined. Permanently. Completely free, no charges.
-
- 4) Attacks launched against this server are logged, analyzed,
- identified, and will most likely result in your information being
- provided to the authorities. Trust us; it's not worth it.
-
- 5) TOR Exit nodes are not permitted to use this server. If we
- use our real IP addresses, then so must you.
-
- 6) Non-abusive bots are allowed a maximum of 3 connections per IP
- or 3 connections per user per /24. Don't try to avoid this
- restriction by getting shells with multiple idents; we'll find
- out. Exceptions will be granted on a case by case basis within
- the bounds of DALnet's AUP.
-
- 6b) ABSOLUTELY NO SHELL AD BOTS / PARK BOTS WILL BE ALLOWED ON THIS
- SERVER. Such bots, their owners, and their parent net ranges
- will be permanently k-lined. We sponsor a chat server, not a
- place for you to make money. Get a job and move out of your
- mom's house.
-
- 7) Above all, remember - this is IRC. It's meant to be fun; not a
- war zone. If you are determined to argue, break rules, whine, or
- flood, then perhaps IRC isn't the place for you. Remember that
- the use of this server is a privilege - not a right - and that
- it is easily possible for that privilege to be revoked.
