Seems FortuneJack has been banned (most likely temporarily for sending PMs to many users)
You're late

:
Based on the modlog it looks like FortuneJack is banned.
Dear Users, our FortuneJack account has been banned. we are working with forum admins to resolve this issue. We launched targeted PM giveaway (80 PM's were sent), rewarding active users with 0.01 BTC. Looks like some users reported it as a spam and our FortuneJack account got banned automatically. We can still read your PMs but unfortunately we can't respond for the time being. We hope to resolve this issue with forum administration very soon. Please note that it will not effect Signature Campaign or any other activity in any way
Well, you should also quote the following good news about his un-ban.

Hi, We got the message that we will be able to post with our FortuneJack account in maximum 5 days.
