I won't upvote this as per your request, but I did pay to promote it.
While your behavior may be disappointing, I am glad to see that you are owning your actions and appear to value this unique platform enough to begin undoing the damage those actions have caused.
If you can provide an example for others of how to correct wrong behavior, maybe some good can come out of this. Volunteering some time to steemcleaners and offering to compensate the artists you ripped off would make a good start.
