i dont really see any problem here.
It was Richard who got me into pob by giving me some nice upvotes, otherwise i probably woudnt have bothered . he is the founder of the weedcash network here on hive. Or 1 of the founders at least...he doesnt post much that is true but neither does @proofofbrain. It seems like he only auto votes on posts he actually likes anyway.
It seems to me he is helping the community in general.
You should be able to do what you like as long as you not breaking any of the obvious rules.
