Well, I sympathise up to a point, but really, as soon as you start going into the question of what is "proper" for this site and what isn't, you start running into a lot of grey areas, where it's hard to draw a sharp line. I would think it would be very difficult to run the site in such a way that the TOS was applied unambiguously and consistently in every single case. Personally, I'm prepared to cut a little slack here, especially when it comes to things being allowed that indicate a more tolerant rather than a less tolerant policy.
