BTW if you got stuck with coins on c-cex, they've reinstated the wallet now so you can still withdraw your funds.

The SMLY remains delisted -- and they do not respond to support questions.

By all means let them know that you are not happy with the delisting. Ask support; post comments in the chat box; send questions to them on twitter (@CryptoCurrEncyX).

It's not enough for everyone just to dump the coin. It also needs to be pushed forward a bit.
