Hello. It's onealfa, not one.alfa. The proofofbrain.io is the declared front end of POB. If you use it then proofofbrainio is auto-set as the beneficiary at 10% of all your rewards.
Using the proofofbrain.blog (Leprechaun's site), or any other non-front end, AND you use the respective proofofbrain and pob tags, you'll be taxed 20% of only your POB rewards.
I hope this clears up some confusion. Please spread the message. I don't know if this is going to change in the future.
