Yes, @themarkymark's explanation is in the post.

It's actually not what most likely expect. Even a 20% POB beneficiary is less than the 10% by posting on proofofbrain.io as that takes 10% of ALL tokens, not just POB, where as not posting on the site only takes 20% of the POB tokens only.

So in the end, if you use the front end you are giving up 10% of all tokens earned, including Hive. In most cases this is far more.

The POB 'team' is fucking ridiculous.

So by upvoting people who don't use 10% beneficiary you are actually giving twice as much to proofofbrain.io... because you have your Hive/LEO/POB assets separated into various accounts. So upvoting users with the 10% beneficiary to the POB account gives away half as much money to these vipers.

Which is unfortunate because I'm never going to use their frontend lol.
