A generic comment on my posts is likely to get nothing, but I really do not get many of those. The spam rate on Steem is much lower than I might expect given there is a chance to earn from it.
With redfish/minnows they do not have a lot to give out in votes, so I am happy if it goes to people who need it. I have been encouraging that as part of #TenKMinnows. I tell them to not vote on my posts, but they still do. That has no bearing on what votes I give them.
