Let me tell you that this is exactly what I used to think. The only reason why this disappointed me once is that I used to write articles on which I have worked a lot, this one for example that people would not even read if I wasn't using voting bots. And investing a day of work into an article that receives 2 or 3 upvotes in the happy case is really discouraging. This is what makes me give a try to voting bots, at least for the better articles. I suggest you to take your time, try anything you want and if you find it okay, use or not voting bots. Maybe you will get more success without them than I did, I really wish you that!
