Seems like the previous tweets are not wiped, and the profile information is still intact. Even if I’m not a fan of MS or Skype, I reported the tweets as the account being compromised. Good luck, MS.
Browsing my timeline, just stumbled on the latest tweet of Skype. Seems like the official account of @Skype has just been hacked, as of January 1st, 2-2014 – 10.35pm EEST.
