The rest seem to be something moderation may help

Who will moderate? If it is a distributed system and moderation is also distributed bad actors can automate upvotes or whatever means we use for moderation to keep their bad content up.

Some of the few ways abuse can happen

• Crawling false data / misinformation on a topic
• Putting info on search as part of a scam / spam campaign
• Putting false news about events that are happening, or have not happened at all
• Putting false information about a business competitor
• Putting fake reviews about a product

Just a few that I can think off… existing websites have the issues too, but what is different is how existing sites decide relevance and how often said algorithms weed out the bad content . In my opinion a distributed search engine will have a harder time at combating those, and other potentials for abuse, because there is less control about what is getting scanned there is an open policy of who can join the distributed scanning.

community for commercial sysadmin type stuff, but the ones I’ve seen are all pretty dead Why not just start putting links / posts to make those active. I am planning to do this for a Postgresql feed.

I think we will need a few more lawsuits such as Apple has agreed to pay $95 million to settle a lawsuit alleging that its virtual assistant, Siri, recorded users’ conversations without their consent before this is no longer treated as confirmation bias or people been paranoid.

My wife used to tell me that her adds would change after discussing something and at first I did not believe her, but it just kept happening again, and again. It reached the point that we would put our phones away, discuss something and there is no change in ads about the topic. If we had our phones near adds would change.This would happen on things that we would not see adds for normally. For example we would discuss a trip to a place we have never been and she would start seeing adds about the destination after that.
