These are all valid points. I do think they do a good job warning you, however. I think the only problem is that once you've read one warning, they all sound the same. The only warning that distinctly stands out to me is Mission Space's. I think that one is a bit much, but it gets the point across.
I think that is just because of the intense focus from the media on the "incidents" that have occured and because the CMs get tired of cleaning up the :hurl:
