Well here is a secret to everyone that use bidbots: it is highly probable that you will lose money buying votes.
The competition is too high to get a good vote per value sent to the bot.
But, on the other hand, i do use bots, by my main reason is to try to promote the post.
This is nothing different from what happens on the other social media, but with the big difference that everything is transparent. You can see who is buying votes, and you can flag the post that you think doesn't deserve de money/visibility.
I haven't thought about waiting until 1 hour to give more curation to the voters, but i think i will start to do that... makes more sense.
