Much better to know the rule first before you do an action. sometime you think you are right but in the rules your wrong. and Local rule help you to know what to do and you will not do.
If a 3 day old user with 14 post already knows about rules and users I don't think he is first user. Maybe user number 3-4 ;-)
I did not know what user I was at that time. I just know I did not scam because I don't.
