No they wouldn't stay there if they are doing any bad things, but there are things that are neither bad, nor good.

Would someone care if one isn't doing any good?

There is quite a difference in whales voting someone and bid bots upvotes.

I am not entirely against both or anyone either, I just don't support the idea of bid bot upvoting oneself.

Bid bots would be better if someone gifts a big upvote to others.
