Thank you for your comment!

If I understood it right... To get PAL rewards, the person who upvote you have to do it from palnet.io.. As there are a small number of people with "PAL power" (stake it in your wallet - similar thing to powering up on Steemit), you didn't get any upvotes from there... I suppose that it like that... and the rewards will come when more people start to use it...

Cheers!
