What happens when the bots show up?
Each server individually isn't a great target for spam, since the populations are low, and there isn't a good way to spam outside of your server, because the entire instance can block you.
Not foolproof in the least, but I haven't seen anything more than a dozen individual spam bots in the last two years.
And on the other side, it's a single checkbox to say "I want to filter any bots".
It's neither perfect nor failsafe. But with enough humans to moderate, report and help out, I'm sure it works better than any centralized, algorithmic setup can ever work.
