@Richlv, glad to hear it seems like that! I think it is actually true, not just an illusion
Any time that you put into fixing blurs is highly appreciated by us - be it mistakes by our algorithms or mistakes by other users.
It's part of my job to review blur requests, while when submitting blur requests I am like every other user (so supposed to do it from my own free time). However, also to the perfectionist side, so it has happened a couple of times that when I see faulty blur requests, I have to go and fix them and before I know it I've spent a good 20 minutes on it in the middle of the workday.
Another note, sometimes users request blurs that are not really faces or license plates, but they still get approved because we want to respect our community's sense of privacy and appropriateness (examples: people in swimwear, drying laundry, ads... etc.). Maybe @yubin has something to say what effect this may have on algorithm learning...
