Hi @pangoli. These groups are bound to exist, but sometimes these things are done through error or a lack of knowledge or understanding. At least you have a conscience and you left the group. I think in time, there will just be less space for opportunists, but they do have an eye for an opportunity, so they can often be almost a step ahead of the game, but the bottom line I think is that Steemit is on the whole a success story, but has a few little glitches to sort out, but such is the nature of an organically developed concept.

Thank you for your comment :).
