If people vote for you and you make a lot of money that is not your fault. Enjoy it. Just take some time once in awhile to check out some new posts from people and up vote some stuff. It then doesn't really matter because you'll be helping grow steem power for other people. At least that's how it seems to work. Yet you didn't do ANYTHING wrong in posting. Technically it IS original content which is more than some of us can claim.
EDIT: The most amusing part is that some people posted responses to your post and it is clear they had no idea what it was. :) Kind of funny if you think about it.
