Well, I don't know what guidelines you have in mind and what is meant with those points but the punishments should be harsh, really harsh, IMO.
Only that works, unfortunately.
Like:
1st offense - warning, 1 day forum ban
2nd offense - 1 week forum ban
3rd offense - 1 month forum ban
4th offense - Lifetime forum ban
I think that kind of punishment would be the best deterrence to not break the rules at all.
Show me one person which will do it more than one time...
