Reputation is largely pointless everywhere in my opinion and on Steem it is not much of an indiacator of quality but, could be an indicator of time on platform at the higher points.
It does seem to be important to some people though and because of that it can open some doors or close some doors depending on how they view a person.
I think bidbots should register as such and have no effect on reputation.

Scrap the whole concept as it is useless.
I wrote a couple articles concerning it a long time ago but if bored, you have something to read.

It may be pointless everywhere, especially on Steem, but it still effects how people treat you ;) hehe
How would bidbots register, and what happens if they don't?
yeah, it would have to be voluntary somehow, not going to happen since half of them are run by witnesses.
