There are basic rules and guidelines which are set out. If you break the rules, you get warned. There is no way to argue against it.
It isn't uptight, it's pretty moderate, actually. If the staff were uptight they would've locked and warned you for this thread. Instead, you receive warnings for things which are already against the rules.
This applies to everyone, too.
No spamming, no necro-ing, no trolling, no... you know the rest. The rules of the forums are available for all to see. If you can't abide by them you eventually will get banned.
