You need to watch the video that I just posted here. It is pretty clear that Craig Grant & TrevonJB, as well as their BitConnect website are now being exposed as a complete ponzi scheme and they are frauds.

Furthermore, stop using the "introduceyourself" tag with your posts. I ran into the same kind of resistance myself a couple of weeks ago. That tag is protected and enforced by people on steem who have much more Steem Power than either of us have - so they make the "rules." I suggest you either follow their rules or invest about $50 K into buying more Steem Power so that you can downvote their posts and tell them what you want them to stop doing to you.
Otherwise, just stop using the tag. That's the generally accepted "rule" by the majority of Steemians and you will be fighting a losing battle.
