I'd be cautious about seeing that as good news. I'll always be suspicious of how many posts here are either partially or entirely automated, whether that means automatically reposting stuff from other sites, fully generated text, or just augmenting a human's posting.

I like to think we're too small for most botters to care about us, but who knows! As far as I'm aware, no one service has any reliable tools for spotting generated posts. No way are federated services prepared to deal with the insane influx of bots that would naturally come with being significantly more popular. Seems like all we have are captchas...
