Just wondering if there was a curator hired to do the job on the larger ones for a small percentage of the bid. I know it isn't 'your job to judge' but essentially it is an endorsement of the content on the vote. The removal of the vote is a different thing altogether.
What would be interesting is if a bid comes in and is not approved, the curator still takes the small percentage for doing their job. That way, it is more more likely to attract quality posts since there is an actual cost to it. if all large bidbots did the same, not much shit would make it to trending at least considering there will be a range of curators. What it means is that if the curators are somewhat representative of the platform, trending via bidbot would be representative of the community. Trending requires many bots (mostly) to get to trending so if some curators refuse the bid on shit won't have 1500 dollars on it and pointless won't have 300.
