RE: What is appropriate use of upvote bots? A survey. - My response
My idea behind it? If you have to use a bot to upvote your posts, that automatically tells me that your own content just isn't that good. If you pay for a bot to upvote your post, that also tells me that you personally down even believe your own content is worthwhile.
It is a different story if some other user entirely uses a vote bot to upvote your content, provided you're not also said user as an alternative account trying to game the system. If someone were to really like something I wrote, as to decide to not only reblog it but also vote it and use a vote bot to vote it up as well, I'll consider it a good job.
But I'm only able to tell if said bot is being used on me, because I only control this one singular account, no access to any others. So if a vote bot happens across me because someone paid or bid or whatever, it tells me they think my content is good. But alas, to your perspective, it could very well be me using an alt to vote myself.
That's how I see bots. I'm very iffy on them. And since nobody can personally tell if I own an account that's using a bot to upvote something of mine, I'd personally rather them simply not use a bot to upvote my posts.
