How did you measure that they're the cheapest and easiest? And cheapest and easiest for whom?

I did and I did.

They are "cheapest and easiest" because they're the ones that currently exist. Any other approach would require work on the part of the site owners. If you want them to change that then you're going to have to present a case as to why it's in their interest, not why it's in yours.

Nobody is opposed to you setting up a competing forum with different spam-filtering qualities.

If you already have access to such a great forum, why do you also need access to HN, Reddit, Lobsters etc?
