I managed to see his tweets, where he apologised for his job-posting, by googling for his twittername and looking it up at google cache.
"Apologies for my discriminative job advert. It was totally wrong. Going forwards, we’re adopting a more ethical hiring procedure."
Moreover while I can understand deleting a Twitter account after a Tweetstorm, deleting your professional Linked In profile seems pointless at best, unless I am missing something.
