I rely, as I always have, on the value of my speech to interest folks in what I say.
Given the number of votes you have received, I suspect that your posts, like @ned's and @dan's, do not require buying votes.
You can easily see if this is true by making a post and not buying votes.
If that is unpalatable, I am sure you will not miss my insubstantial upvotes.
@freebornangel has proposed that folks that maintain, as you are here, that purchasing votes is only done to advertise the content to potential viewers can decline payout, in order to not draw down the rewards pool.
That would strongly indicate to me, and probably many others, that your intention was indeed to simply make your content more visible, rather than extract rewards from the pool intended to incentivize creation of quality content.
@ned and @dan typically do this when they post. I have not observed them purchasing votes either.
Thanks for asking!
