The problem with this approach is that it's an extra filter that isn't run by the witnesses, and won't be decentralized. The hot and trending are the only ways to discover content, without a central server.

I agree that UIs should also fight to diminish the visibility given by bot upvotes if they can, but it's not easy as it requires each UI to have it's own separate db to query and sort in the way they want ... Hot and Trending are kinda good, because its the same algorithm than reddit and it's been tested through time.

We can also create processes to not give upvotes (from Hive account@busy.org , Hive account@dtube , i.e ned's delegation) to people who use bid bots in general.
