Yes, they are unworthy posts in a views of a bounty manager or a poster like you here but, the point is that does not mean he should be banned from posting as he has earned no merits. If they are banned it would just make a decent crypto collector unable to post on best crypto forum in the world.
What Value or entertainment does he provide on this forum? how is he a "decent crypto collector" ?
just to confirm -
