I mainly used bid bots as a tool on my contests to get visibility and a lot of community feedback. At that same time, I am also giving away a generous amount of SBD in doing so.
I can see where abusing this can also cause issues as some are just in it for the return and nothing more. Which in turn can push down the visibility of users who can't afford to use bid bots.
