If the other side thinks filters only "work" if they stop *all* spam then their definition is absurd. No filter in any context I'm aware of stops 100% of pollutants. Mempool filters have a clear statistically significant limiting effect. Removing them means they no longer think that effect is worth their cost. And that's where I disagree with them.

The chart you posted looks like a big failure for the minfee filter. 90% of nodes running the filter, and that many got through? It looks like they did very little if anything. Claiming "statistically significant" doesn't make something so. I've yet to see any rigorous statistical analysis from either side, and I don't think the evidence can be gathered from chaindata alone.
The reason most are at 1sat is the default app like Nunchuk or sparrow doesn’t allow less than 1 sats.
This is “the filter” it is a social policy that works reduce undesired behavior.
