beside the long payout wait (~2 months), they had this problem all the time,
No Server for upload avalaible at this moment!
you have to wait for bitshare links and then edit your post AGAIN if you post bitshare together with other filehosts links.
i stop posting bitshare links if i face this no server issue instead waiting time re-editing post, right now 50-60% of my posts now is missing bitshare links.
they also have a big advantage if for whatever reason they decide to close they can save 2 months worth of payout.
