I have not tried any bidbots. And I am not sure I want to.
Paying for promotions services is one thing, buying votes is another. And while I can't promise I won't ever do it, I have only begun my experiments with bots, and I am taking things slowly, to get a good idea of which strategy is most effective for myself.
Based on your comments, it would seem that bidbots may not be a good fit for me.
Sounds like a good plan... Bidbots are essentially the same as minnowbooster -but there is potential to earn a higher ROI (or in my case have a lower ROI)
Yeah I am not to big on them but in some cases I need to for visibility (such as contests), but otherwise I just focus on writing good content.
I also find some people dont like bots and are actually less likely to upvote you if you are using bots all the time. I found without them its more likely your content will get noticed by services such as @curie aswell..
Its a tough situation because I can see the pros and cons of each side
