Now, I understand the importance of having web filters, especially at workplaces. And if a company says that community websites are off-limits for viewing, then I can abide by that.
But from what I've been able to determine some companies are only doing rudimentary blocking. Only disallowing "blank" or "null" category sites, for example. They don't care too much what your site is about, as long as it's classified correctly and doesn't match some criteria that's blacklisted.
And that's what's getting me here. I'm not being blocked because I have "bad" content. After all, it's a clean and benign community home owner association website. I think the most offensive words on it are "crime" and "payable to"...

On the other hand, for example, the CoffeeCup website, including the forum area, is NOT blocked. Nor are the major news outlets, such as CNN, ABC, Fox News, etc.
So, I'm pretty sure I'm being blocked because I have "no" category classification; or a "blank" classification.
So my question for all of you: How do I go about getting my site classified/categorized? Is there a tag I can insert on my pages? Is there some sort of registry that I can visit / sign up at?
Google search is not helpful in this area.
Thanks in advance!
