I'm not sure if it's related to the other recent woes, but the only block explorer I'm aware of for SexCoin last saw an SXC block four days ago. https://chainz.cryptoid.info/sxc/ perhaps with a lack of exchanges, those merge mining sexcoin have turned their miners to DOGE coin which jumped eight-fold a little over four days ago.

No one mining = No block chain = trouble.
