Yeah, it appears some interest in Spartancoin. However, graviex is probably not that good of an exchange for it unless the price is at least 0.2 satoshi, because if it is less than 0.1 sat on unnamed (currently 0.00261 sat), then all that will occur on graviex is something like this.

Sells:
Amount                           Price
24820797 spn                0.000000001 btc

Buys:
Amount                           Price
0 spn                               0 btc

Then it will get delisted.
