Yes as long as the post has the SPT tag or is posted from the SPT site, If you vote on the SPT site (or any other steem clone site) it still drains your Steem Power as well.

There is also a palnet.io and a battlegames.io and others.

Battlegames is for gaming content only. A person could post from Steemit and tag battle / palnet / spt and earn steem/sbd/pal/spt and battle tokens.

again thanks.
