well i think these are not real persons, they are just bots. usually when you add "steemit" as category the potential is very high to get hit by those bots, very annoying. they have to do something against that otherwise there will be no future for steem.

EDIT: the proof of this theory is your post above ;). already 43 upvotes and 0.00$ earned. so sad :( im sorry for you im struggling with the same issue.
