BTW, "proofofbrain" community has nothing to do with Hivewatchers.

HW never endorsed it. It just popped out of the blue.

Hivewatchers follow the concept of Proof of Brain just as Steemcleaners since its inception.

"proofofbrain" community has proven to have nothing to do with the concept that HW follows.
They just nicked the name to make the community look legit.

This community is ridden with plagiarists and scammers who are posting there regularly.
They don't do any due diligence on the content of the posts.
They never really properly explained to their community what "Proof of Brain" means.
