Sorry for the late reply @roleerob,

Question 1: Steemauto is used as a way to automatically distribute the upvotes. I used to make a monthly post where missing upvotes could be reported and where the ones who did not manage to make 3+ posts that week could leave a comment that I than manually upvoted. Steemauto is rarely down and the program for as far as I know had very little missing upvotes so there was no real purpose to continue those monthly posts. There is no real consistent way right now to upvote comments and it's also not really the purpose of the program. I'll make sure to upvote your comments on the posts from the @upvoteshares account and if you have a comment you want to get more visibility on in another post you can always send me a link on discord. I hope that works for you.

Question 2 Valid question and it's something I also though about when starting this project. If I would die right now, it would indeed idle along and continue to give upvotes for as long as steemauto works. Something I will do is make a text file on the usb where the private keys are and write down what needs to be done in case I drop dead. Something else I could do is for example give your (or someone else who is trustworthy on Steemit) the private active keys which can be used to power down and give back all the steem in the account that belongs to everyone. I would have to make a post where the majority of the shareholders have to agree upon this first though.
