Yup,

Indeed the bidbots harm the users in multiple ways as you said and gradually decreases your image among the other users. Using bidbots can also be a sign that you don't have much confidence in your content because of which you wanna use the bots. Or other reason might be of grabbing attension, well that can be achieved in a lot more ways but with this way (using bidbots) you are digging your grave as you would keep losing attention as the other people would be habituated to see you buying votes and would sideline your content and move ahead which directly means you lose attention but initially this was your intention which is now as simple as a nightmare for you.

So Guys Beleive In your CONTENT and TRust on organic Upvotes

Cheers !
