This means that it doesn’t work perfectly and has too many false positives and false negatives. This is unfortunately unacceptable since I don’t want to ban legit blogs, and also want to properly remove spam blogs.

I hope more platforms take note of this. AI seems deceptively suited for spam/abuse detection. Unfortunately, I've yet to see a fully automated process that doesn't make mistakes in some cases. Nearly every case I've seen of a person's obviously erroneous removal from a platform has been the result of giving automated tools too much power.
