With my suggestions, we will be able to separate those who use bidbots for the visibility and those who use it for profit.

What do you think?

What would be the purpose of separating the "visibility bidbot users" from the "profit bidbot users"? The users we see on the trending page are just a small fraction of all bidbot users. Let's say 2% of all bidbot users buy their votes for visibility. Then what?

I agree that the trending page right now is useless and should probably be changed with a better algorithm. But I don't think changing the trending page will have much impact on vote buying.
