<a href="http://justdelete.me/" rel="nofollow">http://justdelete.me/</a> is a good site for looking up these policies. Skype is bad, but not quite in the "Impossible" tier with sites like YouTube, Wikipedia, and Hacker News.
Netflix has the same policy or it did when I wanted to delete my account. Support person instructed me to change the email address to something unknown.
sadly, this is actually not new and has riddled many forums before.<p>skype has never allowed that before and, to my knowledge, never communicated why that is. Or if there maybe is a technical reason for it.
