Honestly, mindless humans are worse than AI zombies, but there is a bit of both here. My ballpark estimate is that 90-95% of posts here are complete trash and should be deleted.
As far as the the Gambling and Altcoin Discussion boards go, yes easily. I believe the problem is the bar for what passes as "not spam" is so low in those sections that shitposters have gotten used to seeing their shitposts stand and now have the courage to shitpost in other sections of the forum... ones that are actually being read by people.
This number comes down to 80% for Bitcoin Discussion and as low as 20% for Dev & Tech discussion

There's nothing we can do about it though as long as the man in charge thinks that there is no problem. Yet another example how centralized control leads to failures.
Ultimately its not a problem as far as the overall existence of the forum is concerned: the bills are paid and all theymos actually has to do is keep the lights on.
But yes, rational people looking for stimulating conversation - who might one day even contribute something positive to Bitcoin - can be easily driven away by all the spam posts about nothing.
I don't think the mods ever delete anything on their own accord, they are acting on reports 99% of the time, so the solution is to just report every piece of garbage post. Maybe if enough of us start doing this and reporting the same posts, we can kind of raise the bar a little bit.
That's all I got.
