Well to be fair, they are moderators for a reason. Their judgement has been trusted to know what is acceptable and what isn't. Not to be that guy, but the first and foremost rule of the forum, as stated by the big man himself:
Respect & Be Helpful —
By far, the most important rule here. Generations of GM enthusiasts have come together through a shared passion for the car and the community, so the golden rule applies: Treat others as you wish to be treated. This means no foul language, insults, or rude remarks towards other members.
We’re here as a family of enthusiasts, and we should act accordingly. And since the site is constantly gaining new members, please go out of your way to help answer others’ questions in an effort to make this an even better community. Shunning new members’ questions or rudely telling others to “search for it” is extremely discouraged.
That being said, I believe the mods here do a pretty good job. If anything, they are on the rather lenient side of things. As a friendly reminder, understanding and perceiving the real intent of ones words behind a computer or phone screen can often be difficult; just because you know you're joking or coming off a certain way, doesn't mean others do. Be respectful and adults. Post to be helpful or constructively criticize. And most importantly, enjoy the best forum on the net!
