I agree totally with your broad point, but wanted to respond to the "I can't believe a user typed..."
Even if your 50,000 people are all pretty smart, you're well out into the range of exceptional circumstances. If I do something once a day my whole life, that's still only 25,000 times. It's pretty easy to imagine somebody on their worst day doing something like that. E.g., You go to visit family, so you're jet lagged. You had a couple of late beers with your brother, so you're hung over. His baby is screaming with colic and the toddler is banging pots together. You're VPNing in from their kitchen table, trying to fill out some form, and in the middle somebody knocks over a glass of juice. You yank your laptop up, help clean up the mess, and then sit back down to finish. While the pot-banging proceeds at full volume.

Madness, sure, but common madness.
