I like what you are doing to clean up the community. Approved you as an witness. Its sad that most of the banned users are from south asian countries as least their username suggested that. I am also from south asia.
I think these people are seeing Steemit as a quick money generating platform rather than contributing to it and creating a community. I often see on Facebook some people are marketing it as such.
I know its time consuming but please keep up the good work.
Thanks mate,
