Dash is freeze in poloniex, why?

When you backport 10,000s of commits from Bitcoin Core while suffering massive code drift due to believing Roger/Jihan/Craig anti-RBF+segwit FUD, something is going to break eventually. Especially when you bolt on a proof-of-stake Masternode kludge layer.
You are still at this icebreaker? You are a machine.
