Steemit doesn’t have a content discovery mechanism than can promote good posts. At least with bid bots, you can take your post reward destiny into your own hands and earn what you feel you deserve.
I do understand that people abuse this by creating low quality posts and receiving high earnings. Does that make bid bots the problem? The trending page itself is an issues as it’s based on earnings rather than something like views or reblogs.
Using bidbots helped me promote this app (What Q&A) and there were times my app post rewards didn’t even reach $1. It’s very disappointing that someone can add value to the steem ecosystem yet receive almost nothing in return. Therefore, bidbots came to the rescue and provided good earnings with also more people knowing about the app.
