Writing things on the Internet is part of human behavior.

What a person says reveals aspects of who they are. The Internet is not some special place that is exempt from all normal expectations of conduct that otherwise hold in meatspace. Just as simply being part of a business enterprise does not exempt one from being judged as a human based on your behavior.

Also note I said "suspect" not "knew for certain" or anything as extreme or decisive as that. Important distinction, and one I chose intentionally when picking that word. :P :)
