Basically, it says "go to help desk, and maybe send us an email."
Note the careful wording of the line about legal problems. I'm trying to tread a fine line here between encouraging people to contact us the right way about real problems, and not encouraging cranks and nuisances.

If this looks workable to people, we'd like to publicise this (slightly) as a place to get concerns dealt with, so companies feel they have somewhere to approach that won't get them bad press in 100 newspapers around the world (as happened to Microsoft). Per Geni's excellent suggestion, we can recruit new en:wp admins to help with the queue :-)
