Violation Reason: Sexually Explicit & Obscene Content

In Yahoo! Answers you may not post, request or link to content or images that are sexually explicit or otherwise offensive.

How is it that the content published by a noble non-profit charity like the Wikimedia Foundation is a "violation" of standards here on Yahoo!?
Update: NOTE: I provided plenty of additional detail beyond the link, including a specific emigration recommendation.
