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.
It is indeed low now. My opinion stems from the time the steem price was high and it was a massive problem then, people were creating many many accounts to farm comment upvotes. If I recognise someone then I am not so fussed. I only get gnarly when I don't recognise the name but I recognise the behaviour.
