Actually I'm a bit of an outlier as far as the witnesses are concerned, I am mainly involved with my team BuildTeam and don't get too much involved with the others, although some to come and mess with me even though I mind my own business, so I'm def not categorised among the group you mention. I do straight honest business and I lease out most of my SP on our company service dlease.io, that way I put SP in the hands of others and spread the power and influence while still getting an investor's return.

Since you are a DJ you might want to check out the OpenSeed Project and Thicket, you should connect with them, I think their product is good for Steem, latest post: https://steempeak.com/@bflanagin/steem-connected-media-service-thicket-update-now-with-over-720-tracks-and-evergreen
