So I got this response from Cryptopia yesterday:
"Thanks for contacting Cryptopia.
While the behavior of many members of the community is one of the reasons for the delisting, there are other issues as well similar to the reasons SAFEX has been delisted from other exchanges.
I apologise for the delay, the wallet is now back online. If you have any SAFEX in your account please withdrawal at your earliest convenience."
If part of the reason is due to the same reasons Bitterex delisted Safex, does this mean other exchanges might reject it on the same grounds?
