if can not fix wallet in polo ,we can not stop that qora will be the one of the dislist coin next time.
It seems like crowetic sent 3 emails to Poloniex already with the fix for the wallet. I would suggest you to just send a support request to the exchange and point them to this thread,asking them if they can fix their QORA wallet.
Poloniex likes to inspect any coin's code that it lists. They might not want to use the new fixed wallet until its code is put on github. Poloniex might quickly fix its wallet after crowetic puts the code on github then sends poloniex another email.
