I'm not sure which curation services are doing this, but I am not really a fan of massive curation accounts. I know people want to either get paid for delegating or to follow a big trail, but getting votes for delegating is effectively paying for them.
My voting is mostly manual with a couple of small trails that I don't get paid for. I delegate to a few projects, but am not bothered about what I get from those. I am fortunate to get decent votes anyway, but that is based on years of activity and engagement.
