Ever wrestle and struggle with writing the Terms of Service of a website? It's an interesting exercise, and I'm not certain that I would recommend it for the faint of heart.
Some preferable endeavors: Jump from a bridge attached by a bungee cord. Launch yourself out of an airplane and glide to the ground with a patch of silk and strings. Ride a wild bronco at the rodeo. I'd write more, but I suspect you get my drift.
To some degree, you're either reiterating, or describing for the first time, the business objectives of an organization, and the anticipated interaction between site visitor and site owner.
