This is information I will be happy to see. I haven't bothered to retract votes that somehow get made on my posts, but I never vote my comments.
Vote buying, self voting, and bots/curation trails, all suck from the common reward pool without contributing to the actual curation of content worthy of votes.
These are problems that devalue the common rewards pool, and this devalues Steemit itself. I'd like to hear proposals that might resolve this issue, before all the trees in England are cut down. Ooops, too late (an example of the rape of the commons that did not get resolved before the commons were devoid of value).
I see that HF19 did reduce inequity some, and this is good, but it merely adjusted the symptoms, and did not address the cause of inequitous concentration of wealth at the expense of the commons.
I have suggested that the wealth of the account holder be not considered for curation, or rewards distribution, in any way. This would make vote buying go away. It would also make all the timing of votes, curation for the sake of rewards alone, etc.. go away.
I have yet to read, despite promises from those I have discussed it with, of any good reason for perpetuating inequitable distribution of wealth from the common rewards pool, or for downvotes.
Other than luring investors to initially fund Steemit, that is, by creating a mechanism from which they can profit. However, traditional investing in stock, for instance, doesn't create payroll taxes inuring to investors, or other mechanisms comparable to extracting funds from the rewards pool, but offered capital gains from the success of the company whose stock was purchased.
This seems to me to be proven to be nominal to attract investment, and would allow content creators and curators to be motivated by the content in their work, rather than tricks that game the system for maximal financial rewards.
That, in turn, would seem to best potentiate Steemit to grow and prosper, which would increase the price of Steem, and reward investors.
Maintaining tools for inequitably extracting wealth from the commons seems to promote the opposite, and I am agin' it.
Thanks for you post!
