I agree with your points here.
I have been against bidbots since they first appeared in 2017
I am now kind of against them, but I must admit that last year when I just got into Steemit I did use randowhale and booster a bit. But randowhale was way more innocent than what bots are nowadays where you can boost your posts to several hundred dollars. And not only that, with BidBots you can make other bidders to lose money if you bid too high, thats just nuts. (please correct me if I am wring, maybe things changed, but it used to be like that a couple months ago)
I totally understand your frustration about seeing users growing their Rep super fast by boosting shitposts like there is no tomorrow < EVEN Witnesses.
I have talked with a Witness that likes to boost a lot of his posts in PM and the answer I always get is "It is for exposure/visibility reasons"
I just don´t see the need to give exposure/visibility to a post about a Fortnite session though... I honestly see that as buying Rep while making a quick buck (not really good money, but it all adds up)
I think that can happen, or maybe they put caps on each round, I have never used so I'm not sure either.
