There's a chance it might not fall on deaf ears. One of the people that runs one of these sites could see it, and consider implementing a similar feature. Though perhaps 3 days isn't enough. There's a habit of some to forget that not everyone checks their email every day, or even every week, or it can get lost in the weeds. I think once a week for 3 weeks would be fine as well.
There's also a chance someone that will eventually implement a service in the future will be shaped by not just your post, but the entire discussion around such things. I myself have commented before on there being a problem with auto-voters, and neglected auto-voting.
I have considered alternative ways of dealing with it. I believe that votes, and their rewards, should be weighted based on voting habits. Someone's vote that votes for every single post by someone should mean less than someone that only votes for that person occasionally, if they have the same or close SP. Similarly if they only vote for a small handful of people. In effect, it would be rewarding people that take effort to go out and vote new people, and rewarding those they vote for for standing out.
The auto-voting isn't the only issue of course. It's just one. Discussing these things makes a real impact, because it gets people talking about them.
Edit:
Forgot to mention that this would be less of a problem in the future if we had some other way of rewarding authors we like, built-in. Like maybe a subscribe button that would pay them weekly or monthly. If you could choose to take that out of your voting power, or pay directly in steem or SBD, then it would be the same for whales, without the issue of voting for crap, and a bonus for minnows, who might not have a ton of SP, but might be willing to put some money aside every month for their favorite authors.
What you are describing falls right in line with the voting algorithm proposed some months ago by @rycharde, and I believe @timcliff has written about the same idea.
I wonder if there will be some redistribution of the reward pool implemented with communities... like each community has their own reward pool versus one big shared pool.
Finding the best ways to ensure that content is rewarded appropriately will likely be the raging debate for the life of the blockchain. hhahaaha
It seems like a lot of people have some of the same ideas in regards to what should be done on here. Hopefully they'll actually implement some of the better ideas, and we can start improving things.
