RE: UPDATE: Problem fixed || We are investigating the glitch that seems to have zeroed out 2-days worth of VYB rewards

If so how come when one doesn't tag their post with #vyb or #verifyyourbrain the post doesn't show on vybranium.com even though they used the proofofbrain frontend or tagged #proofofbrain/#pob?

During these initial few weeks, while we are testing everything out and while the rewards-pool is running at a reduced rate, the smart contract is set to only recognize #vyb and #verifyyourbrain. I will update the initial white paper to reflect this.

And since it doesn't show there does it still receive vyb rewards?

If a post does not show up on the www.vybrainium.com front-end it is not eligible to receive VYB tokens from the rewards pool.

he won't need to do that if simply using the proofofbrain frontend or using the proofofbrain/pob tags would be enough to qualify a post to receive vyb rewards, isn't it?

That is correct and that is the intention (that VYB will function as an extension of POB). However, we wanted to reward those who are actively involved in these early VYB discussions, to set it up so that they benefit directly during this testing / ramp-up stage.
