Chiming in to say that I have the same exact experience :) I work in security, and we use these methods to detect anomalies or classify malicious content or URLs. A silly false positive is embarrassing, even if it happens once. Humans always augment our methods, or we have to set expectations to the customer that we are trading off accuracy for speed. Fast customer support usually helps against false positives too.
