I haven't used a voting bot ever but I can relate to your feeling about manual curating. I already think it is cumbersome let alone how it must be for your manually vote again. Also, and I am not the developer guy, I could perhaps ask if @blockbrothers, the group I am part of, can help you in some way with finding a script for you, or helping you creating one. Our dev is @bennierex, I'll point him to this blog of yours.
