This is all my fault
I hate Google captcha with a passion, so when I'm asked to do it I deliberately spend a minute getting it wrong. If I REALLY want to continue on with the site that is requiring it I might then reluctantly decide to get it right, but usually I'll just abandon it after that.
If enough people would deliberately pollute Google's results like that they would drop it, and stop trying to force people into teaching their AI for free. If their AI ends up not being able to tell a car from a bicycle my job is done!
